| Abstract: | There are several influence factors in response spectrum analysis of super high -rise steel structure,including the selection of calculation model, the conside ration of number of reasonable vibration mode and the choice of combination method. Wuhan International Security Mansion super high-rise building is calcul ated by finite element analysis software ANSYS. The influence factors to the calculation result above are discussed. The study can be served as the refe rences of spectrum analysis of such super high-rise structure using finite elem ent software. |
