Book Synopsis Soil-structure interaction in seismic analysis by : Alexander Tyapin
Download or read book Soil-structure interaction in seismic analysis written by Alexander Tyapin and published by ASV Construction. This book was released on 2019-06-11 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil-structure interaction (SSI) is an important phenomenon in the seismic response analysis. As seismologists describe seismic excitation in terms of the seismic motion of certain control point at the free surface of the initial site, the question is whether the same point of the structure (after structure appears) will have the same seismic response motion in case of the same seismic event. If yes, then seismic motion from seismologists is directly applied to the base of the structure (it is called “fixed-base analysis”), and they say that “no SSI occurs”’ (though literally speaking soil is forcing structure to move, so interaction is always present). This is a conventional approach in the field of civil engineering. However, if heavy and rigid structure (sometimes embedded) is erected on medium or soft soil site, this structure changes the seismic response motion of the soil as compared to the initial free-field picture. Such a situation is typical for Nuclear Power Plants (NPPs), deeply embedded structures, etc. The book describes different approaches to SSI analysis and different SSI effects. Special attention is paid to the Combined Asymptotic Method (CAM) developed by the author and used for the design of NPPs in seismic regions. Nowadays, some civil structures have parameters comparable to those of NPPs (e.g., masses and embedment), so these approaches become useful for the civil structural engineers as well.
Book Synopsis Validation of Seismic Soil-foundation-structure Interaction Analysis of Meloland Road Overcrossing by : Thomas Albert Mar
Download or read book Validation of Seismic Soil-foundation-structure Interaction Analysis of Meloland Road Overcrossing written by Thomas Albert Mar and published by . This book was released on 2013 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this project is to investigate the validity of seismic soil-foundation-structure interaction analysis of a typical California highway bridge structure subjected to near-fault ground motions. A three-dimensional nonlinear finite element model of Meloland Road Overcrossing was developed. The model included a combination of elements including shell elements for the bridge deck. The column and piles were modeled using frame elements. Abutment-backfill and ground soil were simulated using nonlinear springs. The complete bridge system was subjected to three-component recorded free-field earthquake motions. The resulting dynamic response of the bridge model was found to be in close agreement with motions recorded at various locations on the bridge. This validates the practical application and methodology of this project and may be used for evaluating the seismic response of other typical bridges.

This book was released on 2017 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation systematically addresses the modeling, quantifying, and protection of highway bridges against earthquake hazards. Firstly, the research substantially improves the p-y spring based simulation method to predict the seismic responses of highway bridges that accounts for various soil-structure interaction effects. Closed-form formulae are provided for the p-y spring input parameters to capture the bridge-embankment interaction effects, based on which an integrated step-by-step modeling procedure is developed. The procedure is applied to simulate the seismic responses of a well instrumented highway overcrossing and validated against the recorded responses during the 1992 Petrolia earthquake. Secondly, the study derives a response modification factor to quantify the relative impact of liquefaction induced lateral spreading with respect to seismic shaking on column drifts for highway bridges. The column drift response under lateral spreading is correlated to the crust layer energy imposed on the pile foundation at bridge piers. Under seismic shaking, the column drift ratio is directly related to the peak ground acceleration. By normalizing the column drift under the lateral spreading to that of under the seismic shaking, the proposed modification factor captures key features of how columns respond under both lateral spreading and seismic shaking, and offers reliable column drift demand predictions. Thirdly, this study investigates the effectiveness and optimal design of seismic protective devices for highway bridges. Component-level fragility functions are developed by using the probabilistic seismic demand analysis. To transparently quantify the bridge performance at the system level, seismic repair cost ratios are derived to combine damage probabilities, damage ratios and replacement costs of critical bridge components. Thereafter, a multi-objective genetic optimization method with the Pareto optimal concept is employed to identify the optimal design parameters of protective devices. Subsequently, the research derives a consistent performance index to facilitate the performance-based design and optimization of seismic protective devices. By converting the system-level repair cost ratio to be a function of median-level engineering demand parameters, a uniform design surface is generated for various protection designs. The derived surface can be easily implemented in the performance-based seismic protection design and optimization without iteratively updating the design goal when a new group of design parameters are considered. The robustness of the proposed method is examined in a case study to identify the optimal protection designs by using a genetic optimization scheme. Lastly, the study derives the seismic demand models for bridge rocking columns with foundation on rigid supports when subject to horizontal near-fault strong motions. The system equations of motion are derived and solved to incorporate the column flexibility and the rocking impact mechanism. By representing the near-fault ground motions with corresponding pulses, dimensional analyses are carried out to regress the closed-form expressions of system's drift and uplift demands. A rigorous validation process is implemented to demonstrate that the proposed models can be used with confidence to predict the seismic demands of the rocking system directly from structural and ground motion characteristics.

Book excerpt: The Process, Purification and Stack Buildings are collocated safety related concrete shear wall structures with plan dimensions in excess of 100 feet. An important aspect of their seismic analysis was the determination of structure soil structure interaction (SSSI) effects, if any. The SSSI analysis of the Process Building, with one other building at a time, was performed with the SASSI computer code for up to 50 frequencies. Each combined model had about 1500 interaction nodes. Results of the SSSI analysis were compared with those from soil structure interaction (SSI) analysis of the individual buildings, done with ABAQUS and SASSI codes, for three parameters: peak accelerations, seismic forces and the in-structure floor response spectra (FRS). The results may be of wider interest due to the model size and the potential applicability to other deep soil layered sites. Results obtained from the ABAQUS analysis were consistently higher, as expected, than those from the SSI and SSSI analyses using the SASSI. The SSSI effect between the Process and Purification Buildings was not significant. The Process and Stack Building results demonstrated that under certain conditions a massive structure can have an observable effect on the seismic response of a smaller and less stiff structure.

Available in PDF, EPUB and Kindle. Book excerpt: This monograph deals with the problem of dynamic behaviour and seismic response of structures which are designed and constructed in seismic regions. Extensive attention is given to description of measuring methods, methods of evaluation of results and determination of dynamic properties of structures. The questions of linear and non-linear seismic response are solved taking into account the peculiarities of stiffness and damping and the demands of proper seismic design and the protecting of structures against unfavourable seismic effects. There is detailed analysis of torsional sesimic effects on structures with asymmetrical disposition in plan, of the influence of higher axial forces on the seismic response and of the problems of soil-structure interaction. The experimental results are extensively documented, with graphs, tables, photographs and a keyword index. This volume will interest structural engineers, engineers-designers, geophysicists, mechanical and geotechnical engineers. It is intended to serve both readers already acquainted with problems of earthquake engineering and beginners in this field.
