全装配式桁架梁组合楼盖平面内刚性性能分析及评估
Analysis and assessment on in-plane stiffness performance of assembly truss beam composite floor
摘要
Abstract
Finite element (FE) simulation of the reduced scale frame model of a kind of assembly single-tube truss beam composite floor is carried out by using Midas/Gen software.Through the comparison of tested and analytical results,the accuracy of FE model is verified.Based on rigid floor assumption,the simulation analysis of the mechanical and deformation performance for the tested floors is conducted under the floor level force.The study results show that,under the two cases of considering the in-plane stiffness of floor and the assumption of rigid floor,the displacement deviation is great,while the distribution deviation for load is relatively small for the new kind of floor system.The method of ASCE/SEI 41-13 is not suitable,while the standard of deviation 10％ for displacement and distribution of load is acceptable for the analysis and assessment on the stiffness performance of the new kind of floor system.Based on such evaluation index,the kind of assembly truss beam composite floor system belongs to elastic floor system.关键词
