复杂竖向混合结构的交界面楼层反应谱分析
摘要
Abstract
In order to explore the seismic response characteristics of the complex hybrid structure-Chinese Navigation Museum,which consisted of steel structure and concrete structure,seismic analy-sis was carried out by ANSYS program.Spectrum analysis and time history analysis were adopted in the analysis,and the interface floor response spectrum was figured out.The calculation results dem-onstrate that the deformation satisfy the allowable values of the relevant codes.The bottom concrete frame structure has amplification effect on the inputted ground motion,which cause that the accelera-tion inputted on the bottom of steel grid structure is much larger than that on the ground.It is sug-gested that the envelope line of floor spectra under the action of multiple seismic waves should be adopted as the design seismic input spectrum when the steel structure is designed separately.关键词
