Abstract

This paper summarizes estimated seismic response results from three-dimensional nonlinear inelastic time-history analyses of some steel buckling-restrained braced (BRB) structures. SSI, when considered, may lead to larger interstory and residual inter- story drifts than when not. These drifts did not cause failure of columns and of the BRBs, but the BRB beam may fail due to flexure. It was found that the interaction between soil and structure results in a decrease of the fundamental frequency of the response and a modification in the energy dissipation. The aim of this paper is to develop FMRI pattern analysis using voxel selection framework that tends to consider decomposed voxel patterns for building precise classification model to identify brain activity. The common practice usually ignores effects of SSI on seismic behavior of base-isolated structures, accounting on the flexibility of base. Isolated buildings, despite, the recent studies on the base- isolated bridges and structures have shown the effectiveness of soilstructure interaction. Hence, not only for the seismic design but also from economic aspects, SSI might be necessary to be considered in the design of a base- isolate dated building.
