FEA analysis of the seismic properties of the integral structure after adding steel frame storeys

DING Haoran,WANG Qingyuan(Architecture and Environment Academy,Sichuan University,Chengdu 610065,China)  
The analysis of response spectrum on the seismic properties of the integral reinforced concrete frame after adding steel frame storeys by finite element analysis software ANSYS.The effect of changing the number of adding storeys and damping ratio on the seismic properties of the integral structure is analyzed.The result include the changes of structural vibration cycle,main modes,force and displacement before and after adding steel frame storeys.Some suggestions are proposed on seismic design of adding storeys.
