This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation focuses on developing models for ground motion intensity, to formulate improved design spectra for use in assessing the performance of buildings under earthquakes. Most seismic building codes and design guidelines are based on implicit performance goals that structures should achieve. Despite the significant uncertainty in future ground motion occurrence, building codes commonly check a structure's behavior under a single level of earthquake loading, quantified with a design spectrum. However, this explicit design check is often not defined with respect to the performance goals. The objective of this dissertation is to provide the link between the explicit design check and the implicit performance goals. Models for multivariate distributions of ground motion properties are refined (specifically, spectral accelerations at multiple periods and locations) and tractable methods to utilize those models to assess seismic reliability of systems are developed. Using structural reliability approaches, with environmental contours of spectral accelerations at multiple periods, a justification of the use of multiple conditional mean spectra for design checks is achieved. Performance assessment procedures for the response spectrum method as well as nonlinear response history analysis are proposed based on these conditional mean spectra. Finally, this dissertation provides an original spatial cross-correlation model for spectral accelerations at multiple periods, which allows one to conduct the design checks simultaneously for multiple structures in a region.

Available in PDF, EPUB and Kindle. Book excerpt: Performance-Based Seismic Design (PBSD) is a structural design methodology that has become more common in urban centers around the world, particularly for the design of high-rise buildings. The primary benefit of PBSD is that it substantiates exceptions to prescribed code requirements, such as height limits applied to specific structural systems, and allows project teams to demonstrate higher performance levels for structures during a seismic event.However, the methodology also involves significantly more effort in the analysis and design stages, with verification of building performance required at multiple seismic demand levels using Nonlinear Response History Analysis (NRHA). The design process also requires substantial knowledge of overall building performance and analytical modeling, in order to proportion and detail structural systems to meet specific performance objectives.This CTBUH Technical Guide provides structural engineers, developers, and contractors with a general understanding of the PBSD process by presenting case studies that demonstrate the issues commonly encountered when using the methodology, along with their corresponding solutions. The guide also provides references to the latest industry guidelines, as applied in the western United States, with the goal of disseminating these methods to an international audience for the advancement and expansion of PBSD principles worldwide.

This book was released on 2014 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation is a collection of research studies that address challenges in Performance-based Earthquake Engineering (PBEE) and provides solutions to issues of concern to practicing engineers, researchers, city planners, and the insurance industry alike in implementation of PBEE for building structures. Contributions made within this research are four fold: i) An applied solution is provided to reduce the number of ground motion records required to reliably estimating Intensity Measure-Engineering Demand Parameters (IM-EDP) relationship used for building loss estimation. This solution employs classical linear modal analysis to develop a first estimate (i.e. a priori) of IM-EDP relationships, followed by utilizing Bayesian statistics to update these estimates using a small number of nonlinear response history analyses of a detailed model of the building (i.e., posterior). ii) An applied hazard based Regional Seismic Loss Assessment (RSLA) method for buildings is formulated. In contrast to previous research in this field, the proposed RSLA method utilizes a regional rapid seismic hazard disaggregation tool and is computationally efficient and sufficient. iii) A new seismic design methodology is formulized and presented. A set of preliminary Performance-based Seismic Design (PPBSD) tools are developed for four-story reinforced concrete moment-resisting frame (RC-SMRF) office buildings, located in Los Angeles at 475 year ground motion return period by which stakeholders can make informed decisions with regards to the potential risk they may adopt against future earthquakes. iv) An earthquake loss rating system is provided that maps a building's seismic performance to a rating value/index. This outcome can transfer seismic risk metrics to non-engineers in an effective communicative way.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents a case study seismic analysis for the Pacific Earthquake Engineering Research Center (PEER) Tall Buildings Initiative of three design variations of 40 story buckling restrained brace frames: a code based design and two variations of performance based designs with two primary objectives: (1) to assess emerging performance based procedures and (2) to compare the difference in seismic demands between simulated and recorded ground motions on tall structures. Extensive ground motion suites for a site in downtown Los Angeles and detailed nonlinear models for dynamic analysis are developed to better understand the relation of tall building behavior to design requirements and to assess current performance based design practices for tall buildings. Structural response is seen to be most sensitive to variations in strength parameters, especially at high hazard levels, while damping and inclusion of the vertical ground motion components are not as critical. In terms of maximum drift and acceleration, the performance based designs deliver similar or better performance compared to the code based designs but at a lower initial cost, largely due to the more realistic column axial load demands computed in the design phase. Three comparisons between the seismic demands on tall structures due to simulated ground motions and selected and scaled recorded ground motions are made. The first, between extreme simulated ground motions and high hazard recorded motions, shows that the inelastic demand are significantly larger for the simulated motions. The second, between spectrally matched simulated and recorded hazard level motions, shows that the two motions excite similar behavior in tall buildings but are not quantitatively comparable because of higher mode effects. This is likely due to the ground motion pulse period, Tp, which is smaller and less varied for the simulated ground motions. The Third response comparison is made between simulated and recorded motions for the Northridge event and shows that the drift response is slightly larger for the simulated motions. Peak ground velocity and peak ground displacement are strongly correlated to the structural response. These results may be beneficial to ground motion simulators and tall building designers to validate simulated ground motions for use in seismic design.

Book Synopsis Utilization of Physics-based Simulated Earthquake Ground Motions for Performance Assessment of Tall Buildings by : Nenad Bijelić
Download or read book Utilization of Physics-based Simulated Earthquake Ground Motions for Performance Assessment of Tall Buildings written by Nenad Bijelić and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Databases of recorded motion are limited despite the increasing amount of data collected through strong motion instrumentation programs. Particular lack of data exists for large magnitude events and at close distances as well as on earthquakes in deep sedimentary basins. Additionally, databases of recorded motions are also limited in representation of energy at long periods due to the useable frequencies of recording instruments. This lack of data is currently partially addressed through assumption of ergodicity in development of empirical ground motion prediction equations (GMPEs). Nevertheless, challenges remain for calibration of empirical GMPEs as used in conventional approaches for probabilistic estimation of seismic hazard. At the same time, limited data on strong earthquakes and their effect on structures poses challenges for making reliable risk assessments particularly for tall buildings. For instance, while the collapse safety of tall buildings is likely controlled by large magnitude earthquakes with long du- rations and high long-period content, there are few available recorded ground motions to evaluate these issues. The influence of geologic basins on amplifying ground motion effects raises additional questions. Absent recorded motions from past large magnitude earthquakes, physics-based ground motion simulations provide a viable alternative due to the ability to consider extreme ground motions while being inherently site-specific and explicitly considering instances not well constrained by limited empirical data. This thesis focuses on utilization of physics-based simulated earthquake ground motions for performance assessment of tall buildings with three main goals: (1) developing confidence in the use of simulated ground motions through comparative assessments of recorded and simulated motions; (2) identifying important characteristics of extreme ground motions for col- lapse safety of tall buildings; (3) exploring areas where simulated ground motions provide significant advantages over recorded motions for performance-based engineering. To gain confidence in the use of simulated motions for full performance assessment of tall buildings, a 'similar intensity measure' validation study was performed. Structural responses to ground motions simulated with different methods on the Southern California Earthquake Center (SCEC) Broadband Platform (BBP) are contrasted to recorded motions from PEER NGA database with similar spectral shape and significant durations. Two tall buildings, a 20-story concrete frame and a 42-story concrete core wall building, are analyzed at increasing levels of ground motion intensity, up to structural collapse, to check for statistically significant differences between the responses to simulated and recorded motions. Considered demands include story drift ratios, floor accelerations and collapse response. These comparisons yield similar results in most cases but also reveal instances where certain simulated ground motions can result in biased responses. The source of bias is traced to differences in correlations of spectral values in some of the stochastic ground motion simulations. When the differences in correlations are removed, simulated and recorded motions yield comparable results. Moving beyond validation, the thesis also explored areas where the use of simulated motions provides advantages over approaches based on limited databases of recorded motions for performance-based engineering. One such area is seismic risk in deep sedimentary basins which is studied by examining collapse risk and drift demands of a 20-story archetype tall building utilizing ground motions at four sites in the Los Angeles basin. Seismic demands of the building are calculated form nonlinear structural analyses using large datasets (~500,000 ground motions per site) of unscaled, site-specific simulated seismograms. Seismic hazard and building performance from direct analysis of SCEC CyberShake motions are contrasted with values obtained based on 'conventional' approaches that rely on recorded motions coupled with probabilistic seismic hazard assessments. The analysis shows that, depending on the location of the site within the basin, the two approaches can yield drastically different results. For instance, at a deep basin site the CyberShake-based analysis yields around seven times larger mean annual frequency of collapse ( c) and significantly higher drift demands (e.g. drift demand of 1% is exceeded around three times more frequently) compared to the conventional approach. Both the hazard as well as the spectral shapes of the motions are shown to drive the differences in responses. Deaggregation of collapse risk is performed to identify the relative contributions of earthquake fault ruptures, linking building responses with specific seismograms and contrasting collapse risk with hazard. The effect of earthquake ground motions in deep sedimentary basins on structural collapse risk is further studied through the use of CyberShake earthquake simulations in the Los Angeles basin. Distinctive waveform characteristics of deep basin seismograms are used to classify the ground motions into several archetype groups, and the damaging influence of the basin effects are evaluated by comparing nonlinear structural responses under comparable basin and non-basin ground motions. The deep basin ground motions are observed to have larger durations and spectral intensities than non-basin motions for vibration periods longer than about 1.5 seconds, which can increase the relative structural collapse risk by up to 20 percent between ground motions with otherwise comparable spectral accelerations and significant durations. Two new metrics, termed sustained amplitude response spectra (RSx spectra) and significant duration spectra (Da spectra), are proposed to quantify period-dependent duration effects that are not otherwise captured by conventional ground motion intensity measures. The proposed sustained amplitude response spectra and significant duration spectra show promise for characterizing the damaging effects of long duration features of basin ground motions on buildings and other structures. The large database of CyberShake simulations is utilized to re-examine the relationships between engineering demand parameters and input ground motions on structural response. Focusing on collapse response, machine learning techniques are applied to results of about two million nonlinear time history analyses of an archetype 20-story tall building performed using CyberShake ground motions. The resulting feature selection (based on regularized logistic regression) generally confirms existing understanding of collapse predictors as gained from scaled recorded motions but also reveals the benefit of some novel intensity measures (IMs), in particular the RSx spectral features. In addition, the statistical interrogations of the large collection of hazard-consistent simulations demonstrate the utility of different IMs for collapse predictions in a way that is not possible with recorded motions. A small subset of robust IMs is identified and used in development of an efficient collapse classification algorithm, which is tested on benchmark results from other CyberShake sites. The classification algorithm yields promising results for application to regional risk assessment of building performance.

Available in PDF, EPUB and Kindle. Book excerpt: Performance-based earthquake engineering (PBEE) quantifies the seismic hazard, predicts the structural response, and estimates the damage to building elements, in order to assess the resulting losses in terms of dollars, downtime, and deaths. This dissertation focuses on the ground motion selection that connects seismic hazard and structural response, the first two elements of PBEE, to ensure that the ground motion selection method to obtain structural response results is consistent with probabilistic seismic hazard analysis (PSHA). Structure- and site-specific ground motion selection typically requires information regarding the system characteristics of the structure (often through a structural model) and the seismic hazard of the site (often through characterization of seismic sources, their occurrence frequencies, and their proximity to the site). As the ground motion intensity level changes, the target distribution of important ground motion parameters (e.g., magnitude and distance) also changes. With the quantification of contributing ground motion parameters at a specific spectral acceleration (Sa) level, a target response spectrum can be computed using a single or multiple ground motion prediction models (GMPMs, previously known as attenuation relations). Ground motions are selected from a ground motion database, and their response spectra are scaled to match the target response spectrum. These ground motions are then used as seismic inputs to structural models for nonlinear dynamic analysis, to obtain structural response under such seismic excitations. This procedure to estimate structural response results at a specific intensity level is termed an intensity-based assessment. When this procedure is repeated at different intensity levels to cover the frequent to rare levels of ground motion (expressed in terms of Sa), a risk-based assessment can be performed by integrating the structural response results at each intensity level with their corresponding seismic hazard occurrence (through the seismic hazard curve). This dissertation proposes a more rigorous ground motion selection methodology which will carefully examine the aleatory uncertainties from ground motion parameters, incorporate the epistemic uncertainties from multiple GMPMs, make adaptive changes to ground motions at various intensity levels, and use the Conditional Spectrum (CS) as the new target spectrum. The CS estimates the distribution (with mean and standard deviation) of the response spectrum, conditioned on the occurrence of a target Sa value at the period of interest. By utilizing the correlation of Sa values across periods, the CS removes the conservatism from the Uniform Hazard Spectrum (which assumes equal probabilities of exceedance of Sa at all periods) when used as a target for ground motion selection, and more realistically captures the Sa distributions away from the conditioning period. The variability of the CS can be important in structural response estimation and collapse prediction. To account for the spectral variability, aleatory and epistemic uncertainties can be incorporated to compute a CS that is fully consistent with the PSHA calculations upon which it is based. Furthermore, the CS is computed based on a specified conditioning period, whereas structures under consideration may be sensitive to multiple periods of excitation. Questions remain regarding the appropriate choice of conditioning period when utilizing the CS as the target spectrum. To advance the computation and the use of the CS in ground motion selection, contributions have been made in the following areas: The computation of the CS has been refined by incorporating multiple causal earthquakes and GMPMs. Probabilistic seismic hazard deaggregation of GMPMs provides the essential input for such refined CS computation that maintains the rigor of PSHA. It is shown that when utilizing the CS as the target spectrum, risk-based assessments are relatively insensitive to the choice of conditioning period when ground motions are carefully selected to ensure hazard consistency. Depending on the conditioning period, the structural analysis objective, and the target response spectrum, conclusions regarding appropriate procedures for selecting ground motions may differ.

Available in PDF, EPUB and Kindle. Book excerpt: The effect of the earthquake ground motion parameters on the probabilistic loss estimation of buildings is the major interest of this study. For the seismic performance assessment, real ground motion records from the past earthquakes are required. Estimation of repair costs in future earthquakes is the major component for seismic loss analysis. This study addresses the sensitivity of the statistical characteristics of ground motions contributing to the building loss. Among these characteristics are the ground-shaking intensity (Arias Intensity), duration, and frequency at the middle of strong-shaking phase of the ground motion. These parameters are vital in determining the seismic response of the building structure. A fine study on the sensitivity of the seismic response and corresponding loss of the building structure to ground motions model parameters is carried out using Performance-based Earth- quake Engineering and Performance Assessment Computational Tool, respectively. But due to the scarcity of moderate to large earthquakes, the real records fail to match the required characteristics of motions, as there are insufficient set of data available for analysis to be carried out. Even, the of technique scaling ground motions results in overall unrealistic properties. This has led to the simulation of ground motions which will provide the additional and hopefully accurate predicted information on characteristics of the moderate to large earthquakes. Hence, a fully non-stationary stochastic model for strong earthquake ground motion model is considered which employs the statistical characteristics (waveform parameters) as model parameters matched with those of identified for a large sample of recorded ground motions for specified earthquake and site characteristics, to deliver simulated ground motions to examine the building loss metrics, which depends on the uncertainties in various analysis process starting from obtaining Intensity Measure (IM), Demand parameters (EDPs) to the repair cost estimates. From the predictive equations, specified earthquake and site characteristics results in the model parameters.Further, the validity of simulated ground motion time series representing the real ground shaking during future earthquakes is a crucial step. This study employs the hybrid broad- band ground motion simulation applied simulations to validate against the real records. With the help of hybrid approach, making use of wave propagation phenomena and site response characterization, effort has been taken for validation of these simulated ground motions is conducted for the sensitivity of seismic response and loss for these simulated ground motions.
