摘要
Abstract
Slabs play an important role in the anti-seismic design of frame structures.In this paper,a six-story RC concrete frame structure was employed as an exampleandslabs withdifferent thicknesses were setin the structure.Seismic performance of the slab is analyzed focusing onthree aspects:stiffness of the floor,story drift angle and yielding mechanism.Rational modeling of cast-in-place floors of real projects was conducted using SAP2000 software.Modal analysis,response spectrum analysis,pushover analysis (static nonlinear analysis)and nonlinear time history analysis were conducted.The analysis results show that the aseismic performance of the cast-in-place floor slabswith different thicknesses have an obvious effect on the seismic behaviors of the frame structure.关键词
