Earthquake ground motions are at the interface of two disciplines – seismologists predict them, and engineers use them. Oftentimes, engineers do not understand the limitations of ground motion prediction, and seismologists do not understand the effect of ground motions on structures. As a result, there is significant confusion regarding ground motions for design.Site-Specific Ground Motions for Seismic Design of Buildings and Other Structures provides a step-by-step approach to properly conduct site-specific Ground Motion Hazard Analysis (GMHA) and Site Response Analysis (SRA). This book also explains various resources that are available to perform GMHA and SRA. It references several standards to provide a comprehensive approach to generate ground motions for design.Topics includeBackground of design ground motions in the United States,General Procedure (GP) in ASCE 7 and its limitations,Ground Motion Hazard Analysis,Site Response Analysis,Ground motions for the evaluation and retrofit of buildings (ASCE 41),Ground motions for the design of LNG tanks (ACI 376 and API 620 & 625),Ground motions for the design of bridges (AASHTO and Caltrans), andGround motions for the performance-based design of tall buildings (PEER TBI).This book will appeal to geotechnical and structural engineers who need ground motion parameters for liquefaction analyses and seismic design of structures. It will also be highly useful to seismologists, geologists, educators, students, and building code officials.

Designing to the Strongest Ground Motions determines the strongest ground motions from data, rather than predictions, and discusses the design of structures to withstand the strongest ground motions. Future ground motions are highly uncertain, but the response of structures to future ground motions will not be uncertain if structures are designed to the strongest ground motions. Uncertainty is not an option in the design of structures whose collapse can be catastrophic.Topics include Characteristics of collapse-inducing ground motions, including energy-demand and cyclic-demand,Strongest ground motions from more than 200,000 instrument-year of recorded data worldwide,Comparison between predicted and recorded ground motions,Seismic characteristics and analysis of structures, including seismic-toughness and cyclic-capacity,Practical nonlinear analysis of structures,Role of aftershocks and number of cycles in seismic design, andCollapse-proof, rather than collapse resistant, seismic design. Through this book, Dr. Malhotra provides valuable insights and new ways of thinking for structural and geotechnical engineers, architects, seismologists, insurers, regulators, educators, and policymakers.

This book describes methods used to estimate forces and deformations in structures during future earthquakes. It synthesizes the topics related to ground motions with those related to structural response and, therefore, closes the gap between geosciences and engineering. Requiring no prior knowledge, the book elucidates confusing concepts related to ground motions and structural response and enables the reader to select a suitable analysis method and implement a cost‐effective seismic design.Presents lucid, accessible descriptions of key concepts in ground motions and structural response and easy to follow descriptions of methods used in seismic analysis;Explains the roles of strength, deformability, and damping in seismic design;Reinforces concepts with real‐world examples;Stands as a ready reference for performance‐based/risk-based seismic design, providing guidance for achieving a cost-effective seismic design.
