Book excerpt: The seismic behavior of reinforced concrete shear walls in Chile generally demonstrated adequate performance as seen from the response of most Chilean multistory shear-wall reinforced concrete buildings after the 1985 and 2010 earthquakes. While shear walls are widely used in building construction, models for simulating the nonlinear response of shear walls have seen limited advances. The need to accurately model shear wall behavior is becoming more important as increased confidence in the seismic behavior of RC walls has led to more relaxed requirements for reinforcement and confinement of typical wall configurations. For example, walls built prior to the 1985 earthquake in Chile were based more on traditional practice and were not necessarily enforced by seismic codes. The majority of post-1985 construction was based on ACI-318 guidelines with relaxed provisions for the confinement of the walls. The changes in the structural configurations and reinforcement details of post-1985 shear-walls in Chile resulted in different behavior and observed damage compared to the pre-1985 walls. In this study, typical Chilean walls are modeled and analyzed so to evaluate the effectiveness of a wall macro-model developed to reproduce the observed behavior of those walls during the 2010 Chilean earthquake. Due to its simplicity and lower computational cost, a multi spring macro-model is used for the simulation. Since the modeling of an entire building presents numerous modeling and computational challenges, a 2D section of the building is modeled using OpenSEES. The calibration of the 2D section model is performed through comparison of the dynamic properties with a 3D elastic model of the entire building developed in SAP2000. The macro-model development includes recommendations for modeling shear behavior of selected structural walls. The research also provides guidelines for calibrating the spring properties of the macro-element as a function of the slenderness ratio of the wall, and the wall web reinforcement ratio. Findings from the study will be useful in advancing nonlinear simulation models for analysis of shear wall structures.

Book Synopsis Seismic Performance, Modeling, and Failure Assessment of Reinforced Concrete Shear Wall Buildings by : Zeynep Tuna
Download or read book Seismic Performance, Modeling, and Failure Assessment of Reinforced Concrete Shear Wall Buildings written by Zeynep Tuna and published by . This book was released on 2012 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reinforced concrete structural (shear) walls are commonly used as lateral load resisting systems in high seismic zones because they provide significant lateral strength, stiffness, and deformation capacity. Understanding the response and behavior of shear walls is essential to achieve more economical and reliable designs, especially as performance-based design approaches for new buildings have become more common. Results of a case study of 42-story RC dual system building, designed using code-prescriptive and two different performance-based design approaches, are presented to assess expected performance. Median values and dispersion of the response quantities are, in general, well-below acceptable limits and the overall behavior of the three building designs are expected to be quite similar. However, the ability to define shear failure and collapse proved difficult and provided motivation to conduct additional studies. For both design of new buildings and evaluation/rehabilitation of existing structural wall buildings, an accurate assessment of median (expected) and dispersion of wall shear strength and deformation capacity are needed. A wall test database (124 specimens) was assembled to investigate the influence of various parameters on wall shear strength and deformation capacity, and to recommend alternative relations for strength and deformation capacity depending on expected wall behavior. Test results indicated that ACI 318-11 underestimates the shear strength of the shear-controlled walls. Mean curvature ductility ratios were obtained as about 3 and 7 for shear- and flexure-controlled walls, respectively. The new relations will allow improved damage and failure assessment of buildings utilizing structural walls for lateral load resistance. Failure assessment of RC shear walls also was conducted for the 15-story Alto Rio building which collapsed in the 2010 Chile earthquake. Possible reasons for collapse were identified using post-earthquake observed damage, structural drawings, and nonlinear static and dynamic response analyses. Analysis results indicate that collapse was likely influenced by various factors, including compression failure at the web boundary of T-shaped walls on the east side of the building, large shear demands at the filled-in corridor walls at the first level, and tensile fracture and splice failures at the west side of the building. Nonlinear modeling and analysis of the four-story RC building that was tested on E-Defense shaking table (2010) was investigated to assess current modeling approaches and assumptions, and to identify issues that require additional study. Including concrete tension strength, stiffness degradation, and strength degradation significantly improved the correlation between the analytical and test results.

This book was released on 2014 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Past earthquakes have shown examples of unsatisfactory performance of buildings using reinforced concrete structural walls as the primary lateral-force-resisting system. In the 1994 Northridge earthquake, examples can be found where walls possessed too much overstrength, leading to unintended failure of collectors and floor systems, including precast and post-tensioned construction. In the 2010 Maule Chile earthquake, many structural wall buildings sustained severe damage. Although Chilean design standards result in different reinforcement detailing than is common in U.S. walls, the failure patterns raise concerns about how well conventionally reinforced structural walls in U.S. buildings will perform during the next earthquake. Alternative wall design philosophies that offer more predictable response, with better damage control, should be investigated. After the Mw 8.8 Chile earthquake, the 15-story Alto Rio building in Concepción sustained failures near the base, overturned, and came to rest on its side. The collapse of the Alto Rio building was significant because it was designed using the Chilean Building Code NCh433. Of96, which requires the use of ACI 318-95 for design of reinforced concrete structural elements intended to resist design seismic forces. The failure of the Alto Rio building is significant for many reasons. It is the first modern shear wall building of its type to collapse by overturning during an earthquake. The building is studied using forensic data and structural models of the framing system subjected to earthquake shaking. The study identifies the likely failure mechanism and suggests areas for which design and detailing practices could be improved. The capabilities and shortcomings of the analyses to identify details of the failure mechanism are themselves important outcomes of the study. A second study explores the behavior of structural wall buildings using unbonded post-tensioned structural walls. Such walls offer the opportunity to better control yielding mechanisms and promote self-centering behavior. The study focuses on the measured responses of a full-scale, four-story building model tested on the E-Defense shaking table in Japan. The seismic force-resisting system of the test building comprised two post-tensioned (PT) precast frames in one direction and two unbonded PT precast walls in the other direction. The building was designed using the latest code requirements and design recommendations available both in Japan and the U.S., including the ACI ITG-5.2-09. The test building was subjected to several earthquake ground motions, ranging from serviceability level to near collapse. Analytical studies were carried out to test the capability of the structural models to replicate behaviors important to structural engineers, and to assess whether available analysis tools are sufficient to model dynamic behavior that results when a full-scale building is subjected to realistic earthquake ground shaking. Measured response data from such an outstanding test provides an opportunity to fully understand the response characteristics of PT walls and assess the ability of nonlinear analytical models to reproduce important global and local responses, including three-dimensional system interactions, both prior to and after loss of significant lateral strength. Moreover, this study to assess behavior and system interaction of PT walls leads to improvements of the current design ideas and performance expectations. The present study examines both the collapse of the Alto Rio building in Chile and the shaking table tests of the unbonded post-tensioned wall building in Japan. The collapse study suggests areas of improvement in current design and detailing practice. The shaking table study suggests an alternative approach to design of shear walls in buildings. Both studies demonstrate the use of modern structural analysis tools to interpret building responses to earthquake shaking. Taken together, the studies provide added confidence in earthquake simulation capabilities and demonstrate alternatives for designing earthquake-resistant buildings that use structural walls.

This book was released on 2019-08-30 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonlinear analysis methods such as static pushover or limit analysis until collapse are globally considered reliable tools for seismic and structural assessment. But the accuracy of seismic capacity estimates--which can prevent catastrophic loss of life and astronomical damage repair costs--depends on the use of the correct basic input parameters. Tools to Safeguard New Buildings and Assess Existing Ones Seismic Design Aids for Nonlinear Analysis of Reinforced Concrete Structures simplifies the estimation of base structural parameters and enables accurate evaluation of proper bounds for the safety factor. Many design engineers make the relatively common mistake of using default properties of materials as input to nonlinear analyses without realizing that any minor variation in the nonlinear characteristics of constitutive materials, such as concrete and steel, could result in a solution error that leads to a disastrously incorrect assessment or interpretation. To achieve a more accurate pushover analysis and improve general performance-based design, this book: Reviews relevant literature to help engineers conduct structural seismic assessment Includes design curves, alleviating the need for complex mathematics Offers supplementary online tools to aid in computing any parameter Provides complete computer coding used to obtain building collapse multipliers Reassessing key inputs, this book analyzes boundaries using a detailed mathematical model based on international codes. It proposes design curves and tables derived from the authors' studies, detailing modeling numerical procedures step by step. The authors include analytical bounds of the structural safety factor for some typical frames, making this work a sound and valuable tool for assessment or desi

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates the seismic performance of hybrid Shape Memory Alloy (SMA)-steel reinforced concrete shear walls containing Nickel-Titanium (Ni-Ti) superelastic SMA as alternative reinforcement in the plastic hinge region. This wall system permits self-centering with high levels of energy dissipation and significant reduction of permanent deformations. Conventional steel-reinforced concrete shear walls were designed for a prototype 10-storey office building, assuming seismic design scenarios in eastern and western Canada. Equivalent hybrid SMA-steel reinforced concrete shear walls were defined following the designed cross-sections of the conventional walls. Full-scale, 2-D finite element models of the walls were developed and subjected to nonlinear, static and time-history analyses, employing historical and simulated ground motion records for the latter. The numerical results confirmed the superior self-centering capacity of the hybrid SMA-steel reinforced walls, showing potential to optimize the seismic performance of reinforced concrete buildings, particularly in high seismic zones, by controlling residual deformations and reducing damage.
