Abstract There is a sparse number of credible source models available from largemagnitude past earthquakes. A stochastic source-model-generation algorithm thus becomes necessary for robust risk quantification using scenario earthquakes. We present an algorithm that combines the physics of fault ruptures as imaged in laboratory earthquakes with stress estimates on the fault constrained by field ...

Soil-structure interaction (SSI) could affect the seismic response of structures. Since liquid storage tanks are vital structures and must continue their operation under severe earthquakes, their seismic behavior should be studied. Accordingly, the seismic response of two types of steel liquid storage tanks (namely, broad and slender, with aspect ratios of height to radius equal to 0.6 and 1.85...

Abstract Coseismic landslides are observed in higher concentrations around surface-rupturing faults. This observation has been attributed to a combination of stronger ground motions and increased rock mass damage closer Past work shown it is difficult separate the influences from strong on landslide occurrence. We measured coseismic off-fault deformation (OFD) zone widths (treating them as prox...

ABSTRACT We present a modeling technique for generating synthetic ground motions, aimed at earthquakes of design significance critical structures and motions distances corresponding to the engineering near field, in which real data are often missing. use dynamic based on finite-difference approach simulate rupture process within fault, followed by kinematic generate motions. The earthquake sour...

Base isolation has been used as one of the most wildly accepted seismic protection systems that should substantially dissociate a superstructure from its substructure resting on a shaking ground, thereby sustainably preserving entire structures against earthquake forces as well as inside non-structural integrities. Base isolation devices can operate very effectively against near-fault (NF) grou...
