| Abstract: | In this thesis, the sub-structure technique is adopted to perform nonlinear planar seismic response analysis considering soil-structure interaction for high-rise frame structures with box foundation or raft foundation resting on natural foundation soils. The dynamic impedance coefficients of foundation are determined by a set of approximate formulas which are obtained by fitting mathematical expressions to accurate numerical solutions. The upper-structures is modeled with the inter-story bar-system model. The nonlinear planar seismic response analysis for a 12-story high-rise reinforce concrete frame structure is performed and the effects of some factors such as different sites, different earthquake inputs on the nonlinear seismic response of the structure are discussed. |
