The Elastic Analysis On Seismic Response Of The High-rise Building With Slab-Opening

This thesis summarized systematically developing high-rise building and analysis on seismic response study at present in our country and overseas. The theory about analysis on seismic response of the high-rise building is summarized, for example,the theory of earthquake engineering,analysis method of dynamics of structures,finile flement theory and so on.This thesis's researches are carried out based on an actual engineering case,6 models with different modality of opening hole are made.SAP2000, a FEA software, is used to conduct analysis on seismic response of the slabs with opening of high-rise building, including :l)Modal analysis. The dynamic characteristics of the building is displayed, then the torsion effect is evaluated.2) The elastic analysis under frequently earthquake. This article selected three earthquake waves and a response spectrum to analyse. The displacement of the top floor, the relative displacement and displacement angles of the adjacent floors, the internal force of the columns and the stress of the slabs belong to each model have been compared.As compared large numbers of models calculating result, this thesis identifies the mechanism through which the slab-opening's horizontal position, size, and height affect performance of seismic response,and some useful conclusions from the result are darwn.
