Analysis On Seismic Behavior Of Vertical Irregular High-rise Buildings

Earthquake is a kind of natural disaster which is difficult to avoid.About 5 million earthquakes occur each year on the earth,the experiences of the strong earthquakes that the irregularity of the building structure affect the magnitude of the damage caused by the earthquake to a large extent.High-rise buildings in the city are restricted by the shape of the block and the surrounding environment.Its architectural scheme may be a variety of irregularities.Aiming at irregular high-rise buildings,it is necessary to use a variety of mechanical models for seismic analysis.And the elastic time history analysis method,elastic plastic analysis under rare earthquake is necessary.The seismic analysis of engineering examples,by judging the irregular building,TAT,SATWE,PMSAP by comparing three different mechanical models of seismic analysis,seismic calculation selection of appropriate mechanical model.The first vertical soft layer is irregular,weak position adjustment between the upper and lower layer stiffness ratio,the seismic analysis to the seismic performance of building structure has improved,and then the vertical irregular high-rise building with elastic time history analysis under major earthquake and the elastic-plastic analysis,the irregular high-rise the building in the earthquake and rare seismic performance under earthquake.Then,from the position of the weak layer and the vertical receiving layer of the irregular structure in the vertical direction,the seismic calculation of several schemes is carried out.Finally,according to the research results of this paper,the structural adjustment of the vertical irregular high-rise building is summarized,which makes the structure have better seismic performance.
