Presented here is an analysis of the effects of soil-foundation-structure interaction (SFSI) on seismic response of highway bridges. Of particular importance is the issue of input motions, their scaling and application to the SFS models. The analysis presented in this paper addresses the influence of inelastic behavior of both the soil and the structural components during seismic response evalu...

We have carried out numerical simulations of seismic ground motion radiating from a mega-earthquake whose rupture process is governed by a multi-scale heterogeneous distribution of fracture energy. The observed complexity of the Mw 9.

Following an earthquake, ground motion time series are needed to carry out site-specific nonlinear response history analysis. However, the number of currently available recording instruments is sparse; thus, at uninstrumented sites must be estimated. Tamhidi et al. developed a Gaussian process regression (GPR) model generate given set recorded motions surrounding target site. This GPR interpola...

With advances in computational capabilities and refinement of seismic wavepropagation models in the past decade large three dimensional simulations of earthquake ground motion have become possible. The resulting datasets from these simulations are multivariate, temporal and multi-terabyte in size. Past visual representations of results from seismic studies have been largely confined to static t...

Cylindrical liquid storage tanks are considered as vital structures in industrial complex whose nonlinear dynamic behavior is of crucial importance. Some of these structures around the world have demonstrated poor seismic behavior over the last decades. There are several methods and techniques for rehabilitation and reducing damages in these structures which among them passive control devices, ...

The earthquake-induced displacement of sloping soil mass is an important indicator co-seismic landslide initiation. In this paper, improved Newmark model that considers the accumulation dynamic pore water pressure (DPWP) in caused by both vertical and horizontal ground motions proposed. can quantitatively describe changes seismic yield acceleration near-saturated infinite slopes. Three differen...

Abstract After the occurrence of a large earthquake, engineering seismologists are often requested to estimate strong ground motions at site where motion data were not obtained. The goal this study was test ability class methods that uses Fourier phase characteristics for post-earthquake estimation, making use precious opportunity provide by ESG6 Blind Prediction Steps 2&3. It also part per...
