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.

As recognized universally by both seismology and earthquake engineering communities, the amplitude and frequency content of ground motions are influenced by local site effects, including the effects of near-surface geologic materials, surface topographic and basin effects, and so on. Strong linkage between seismic site effect and earthquake damage has been commonly demonstrated from many past earthquakes. Therefore, quantitative and reliable evaluation of the seismic site effect is one of the crucial aspects in seismic hazard assessment and risk mitigation. With the significant advancement of modern seismic monitoring networks and arrays, huge amounts of high-quality seismic records are now being accumulated. This encourages us to measure the site responses and its associated uncertainty for selected seismic stations by some record-dependent approaches, such as horizontal-to-vertical spectral ratio (HVSR) measurements, generalized spectral inversion (GIT) methods, etc. Machine learning techniques also show significant promise in characterization of the near-surface geologic properties and prediction of site response. These data-driven approaches help us to better understand the physics of spatial and temporal variabilities of ground motions. Due to more and more site-specific data being captured, invoking non-ergodic assumptions in seismic response analysis has recently been a topic of great interest in the community. For specific site response analysis, numerical simulations are carried out to model the dynamic process of seismic waves propagating and scattering in the subsurface strata. With development of modeling capacity, great efforts have been taken to evaluate quantitatively the complex 2D and 3D effects on seismic site response.

One-Dimensional (1D) seismic ground response analysis is the most commonly performed analysis in geotechnical earthquake engineering. However, previous studies have shown a troubling fact that only a small fraction of sites are modeled well by 1D analysis. The objectives of this research are to assess the site-specific suitability of 1D analysis by identifying the issues that hinder the performance 1D analysis and to develop approaches to better match the observed sites response. The downhole array technique is used in this work to evaluate 1D analysis because it provides the most direct observations of how seismic waves are modified by the subsurface soil and rock. An important phenomenon in downhole array analysis is the potential presence of pseudo-resonances, which has not been effectively taken into account in previous studies and which affects the assessment of the accuracy of 1D analysis. The first part of this research provides insights into the cause and effect of pseudo-resonances and an approach is outlined to distinguish true-resonances from pseudo-resonances. The small-strain damping (D [subscript min] ) is a key parameter in linear ground response analysis and using laboratory-measured values tend to over-predict the response because it does not account for wave scattering present in the field. The second part of this research focuses on methods of increasing the D [subscript min] values in the profiles to better match observed site response, with the site response evaluated in terms of different ground motion characteristics. Alternatively, the randomization of shear wave velocity profiles is also assessed to provide more insights into the variable seismic properties at a site. A hypothesis that links the level of increased damping to the level of spatial variability in materials implied by the geologic conditions is proposed. To broaden the application of the 1D analysis, it is crucial to be able to identify sites that can be modeled accurately by 1D analysis. A taxonomy scheme is developed that classifies sites into different groups based on the similarity in their responses in terms of being modeled well by 1D analysis. This classification system is based on downhole array data but can be applied to non-downhole array sites. The taxonomy results presented in this study show that an increased portion of sites are suitable for 1D analysis.
