Control Of Trosional Response Of The Irregular Rectangular Plane Of Hing-rise Buildings

With the rapid development of economy in the word, more and more high-rise buildings appeared.at present, a large number of complex shape and irregular high-rise buildings are increasing .scholars from various countries had pay great attentions and extensive researchs to the seismic design and analysis for such structure.However, China is an earthquake active country, such as the 2008 wenchuan earthquake, the 2009 yushu earthquake in qinghai and so on, all give countries and people's lifeproperty caused heavy losses, so the deep study of earthquake resistant behaviour of asymmetric structure is of great significance.Through analysis of a planar irregular long form high-rise steel reinforced concrete frame a shear wall structure, using the finite element software SAP2000 gm now on its finite element static and dynamic analysis, to this kind of irregular high-rise building structural dynamic characteristics and seismic stress situation in details when the study. Thus the concept of this kind of structure more profound cognition and understanding, provide the basis for the structural design, and for further research work to lay the foundation. On specific model structure when the elastic dynamic process model structure analysis method, the cycle of the selected three seismic waves than under the action of displacement ratio, interlayer displacement Angle etc the main factors affecting the structure reverse structure is improved, and finally gives the measures and methods of torsion effect, put forward considering the seismic design of the torsion effect of suggestions.This text also research and discusses the principle,ssupposing,putting into practice step,merit and shortcoming, now development conditions,and principle of seismic performance evaluation of static elastoplastic analysis method.
