This study aims to analytically implement base isolation with soil–structure interaction (SSI) on a sample structure and develop very simple solution add these combined effects into the mass, damping stiffness matrices of structure. A spectrum analysis is also carried out considering base-isolated structures SSI. Dynamic simulations are performed throughout study. In simulations, three shear fr...

In this paper, the efficacy of magnetorheological (MR) dampers for seismic response reduction is examined. To investigate the performance of the MR damper, a series of experiments was conducted in which the MR damper is used in conjunction with a recently developed clipped-optimal control strategy to control a three story test structure subjected to a one-dimensional ground excitation. The abil...

Abstract— Though the structures are supported on soil, most of the designers do not consider the soil structure interaction and its subsequent effect on structure during an earthquake. Different soil properties can affect seismic waves as they pass through a soil layer. When a structure is subjected to an earthquake excitation, it interacts the foundation and soil, and thus changes the motion o...

In the 2007 Niigataken Chuetsu-oki earthquake, soil settlement, considered to be a result of relative displacement between and structure, occurred alongside buildings at Kashiwazaki–Kariwa nuclear power plant. The objective this study is evaluate accurately influence nonlinear behavior soil-structure interface on response reactor building using three-dimensional finite element model. To achieve...

-Heterogeneous fault motion of the 1993 Hokkaido Nansei-Oki earthquake is studied by using seismic, geodetic and tsunami data, and the tsunami generation from the fault model is examined. Seismological analyses indicate that the focal mechanism of the first 10 s, when about a third of the total moment was released, is different from the overall focal mechanism. A joint inversion of geodetic dat...

We present a simple nonlinear model of shear-beam building that experiences large deformations and collapse when excited by pulses strong earthquake ground motion. In this paper, we introduce the show its properties can be selected to consistent with damage observed in seven-story hotel San Fernando Valley Los Angeles metropolitan area during 1994 Northridge earthquake. also an example excitati...
