In the last ten to fifteen years a vast amount of research has been undertaken to improve on earlier methods for analysing the seismic reliability of structures. These efforts focused on identifying aspects of prominent relevance and disregarding the inessential ones, with the goal of producing methods that are both more efficient and easier to use in practice. Today this goal can be said to be substantially achieved. During these years scientific activity covered all of the many aspects involved in such a multi-disciplinary problem, ranging from seismology, to geotechnics, to structural analysis and economy, all of them to be consistently organised into a probabilistic framework. As the output of this research was dispersed into a multitude of technical papers, fib Commission 7 thought it worthwhile to select the essential aspects of this large body of knowledge and to present them into a coherent and accessible document for structural engineers. To this end a task group of specialists was formed, whose qualifications come from their personal involvement in the above-mentioned developments throughout this period of time. From its inception the group decided that the bulletin should have had a distinct educational character and provide a clear overview of the methods available. The outcome is a compact volume that starts by introducing the concepts and definitions of performance-based engineering, continues with two chapters on assessment and design, respectively, presenting the methods in detail accompanied by illustrative examples, and concludes with an appendix with sample programming excerpts for their implementation. It is believed that at present fib Bulletin 68 represents a unique compendium on probabilistic performance-based seismic design.
This book provides a new design and evaluation framework based on slope Stochastic Dynamics theory to probabilistic seismic performance for slope engineering. For the seismic dynamic stability safety of slope, it shifts from deterministic seismic dynamic analysis to quantitative analysis based on nonlinear stochastic dynamics, that is, from qualitative to the description of stochasticity of earthquake excitation that meet the needs in related design specification and establish a performance standard. In the nonlinear dynamic time history analysis of slope subjected to seismic ground motion, the term “randomness” is used to express the uncertainty in the intensity and frequency of earthquake excitation for slope engineering dynamic seismic performance. It mainly includes seismic design fortification standard, corresponding ground motion excitation, performance index threshold, and slope deterministic nonlinear seismic dynamic response. Even more than that, the seismic dynamic large deformation approaches of the whole process and comprehensive analysis for flow analysis after slope instability failure. Eventually, the probabilistic seismic dynamic performance of the slope engineering will be characterized by nonlinear dynamic reliability.
The costs of inadequate earthquake engineering are huge, especially for reinforced concrete buildings. This book presents the principles of earthquake-resistant structural engineering, and uses the latest tools and techniques to give practical design guidance to address single or multiple seismic performance levels. It presents an elegant, simple and theoretically coherent design framework. Required strength is determined on the basis of an estimated yield displacement and desired limits of system ductility and drift demands. A simple deterministic approach is presented along with its elaboration into a probabilistic treatment that allows for design to limit annual probabilities of failure. The design method allows the seismic force resisting system to be designed on the basis of elastic analysis results, while nonlinear analysis is used for performance verification. Detailing requirements of ACI 318 and Eurocode 8 are presented. Students will benefit from the coverage of seismology, structural dynamics, reinforced concrete, and capacity design approaches, which allows the book to be used as a foundation text in earthquake engineering.
Solid design and craftsmanship are a necessity for structures and infrastructures that must stand up to natural disasters on a regular basis. Continuous research developments in the engineering field are imperative for sustaining buildings against the threat of earthquakes and other natural disasters. Performance-Based Seismic Design of Concrete Structures and Infrastructures is an informative reference source on all the latest trends and emerging data associated with structural design. Highlighting key topics such as seismic assessments, shear wall structures, and infrastructure resilience, this is an ideal resource for all academicians, students, professionals, and researchers that are seeking new knowledge on the best methods and techniques for designing solid structural designs.
"TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 440, Performance-Based Seismic Bridge Design (PBSD) summarizes the current state of knowledge and practice for PBSD. PBSD is the process that links decision making for facility design with seismic input, facility response, and potential facility damage. The goal of PBSD is to provide decision makers and stakeholders with data that will enable them to allocate resources for construction based on levels of desired seismic performance"--Publisher's description.
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.
Driven by the necessity to meet changing public expectations in the wake of natural disasters, such as earthquakes, the structural engineering community has been moving towards rational, risk-informed, and transparent approaches to structural design, amidst which probabilistic performance-based seismic design (PBSD) has emerged as the most scientific and promising one. The main objective of this research is to formulate a simplified yet rigorous framework for risk-targeted PBSD of Ordinary Standard Bridges (OSBs), which, despite being simple bridges, constitute an integral part of lifeline infrastructure systems, especially in earthquake-prone regions such as California. A seismic performance assessment methodology integrating site-specific seismic hazard analysis, structural demand analysis, and damage analysis in a comprehensive and consistent probabilistic framework is computationally implemented as a modular tool unifying several state-of-the-art advancements related to the field. This tool is used for a parametric probabilistic performance assessment of four different testbed OSBs over a primary design parameter space to investigate the effects of varying key structural design parameters on targeted structural performance measures. Erratic performance levels exhibited by these real-world traditionally designed bridges, compared to expert-opinion-based target performance levels, expose the inconsistency and opacity of current (prescriptive) design principles that do not explicitly state, analyze, and design for risk-targeted performance objectives but implicitly expect them to be satisfied. A comprehensive risk-targeted simplified yet rigorous PBSD method is distilled out and proposed, and its efficacy is validated using four real-world bridges as cases in point. The framework is then enhanced by the inclusion and consistent propagation of pertinent sources of uncertainty (typically ignored in practice) to obtain a more complete picture of seismic performance, thereby leading to a more comprehensive, transparent, and reliable design of OSBs, facilitating effective and risk-informed decision-making in the face of uncertainty. It is believed that the adoption of the proposed PBSD methodology, although non-traditional in its format, will be highly beneficial in the medium to long term. This initial venture will also prove crucial in supporting and fostering future research work and innovative technological developments in bridge infrastructure engineering.
Seismic design of structures is fast turning to performance-based design (PBD) from old codal force-based design (FBD) method. The aim of the book is to expose readers to the meaning and need of PBD, the evolution of PBD to date, its various forms and applications. Various design philosophies and procedures have been described including modelling aspects and hazard considerations backed by examples. Direct displacement-based design (DDBD) and Unified PBD (UPBD) of reinforced concrete (RC) frame buildings, RC dual systems, steel frame buildings and bridge piers have also been explained. The main features of this book are as follows: • Illustrates performance-based seismic design to achieve the design target by performance objective-oriented design procedure. • Covers modern design philosophies, modelling aspects, concepts in nonlinearities and use of supplemental damping devices. • Contains a chapter on seismic safety of nonstructural components. • Describes UPBD design procedure and examples of different structural systems. • Includes application and examples with reference to SAP2000 software. This book is aimed at graduate students, researchers and professionals in civil engineering, earthquake engineering and structural design.
