豎向不規(guī)則高層建筑結(jié)構(gòu)抗震性能分析
[Abstract]:Earthquake is an inevitable sudden natural disaster. There are about 5 million earthquakes on earth every year. The conclusion of experience after several strong earthquakes shows that the irregularity of building structure greatly affects the damage caused by earthquake. Due to the limitation of land shape and surrounding environment, high-rise buildings in cities may have various irregularity. For irregular high-rise buildings, it is necessary to use a variety of mechanical models for seismic analysis, as well as elastic time history analysis to supplement the calculation, and when necessary, the elastoplastic analysis under rare earthquakes is necessary. In this paper, through the seismic analysis of structures of engineering examples, the judgement of irregular buildings and the comparison of seismic analysis of three different mechanical models of TAT,SATWE,PMSAP, the appropriate mechanical models are selected to calculate the earthquake action. Firstly, aiming at the vertical irregularity of the weak layer, adjusting the stiffness ratio between the upper and lower floors of the weak part, the seismic performance of the whole building structure can be improved by seismic analysis. Then elastic time-history analysis and elastic-plastic analysis under rare earthquake are used to ensure the seismic behavior of the whole irregular high-rise building under the action of frequent and rare earthquakes. Then through adjusting the position of the weak story and the vertical intake layer in the vertical direction of irregular building, the seismic calculation of several schemes is carried out, and the comparison and analysis of the parameters such as mode, period and the ratio of interstory displacement are carried out. Finally, according to the results of research and analysis in this paper, the structural adjustment ideas of vertical irregular high-rise buildings are summarized to make them have better seismic performance.
