全装配式桁架梁组合楼盖平面内刚性性能试验研究
Experimental study on in-plane stiffness performance of assembly truss beam composite floor
摘要
Abstract
In order to research the in-plane stiffness performance of a kind of truss beam assembly composite floor (ACF) used in multi-columns bundle tubes structure,four frame models of single-tube with scale of 1/3 were designed (two models for single-story and two-story respectively).Based on the in-plane uniaxial loading experimental study,the in-plane mechanical and deformation performance,development of crack,distribution-transmission performance for floor level force,in-plane stiffness and overall deformation behavior of each floor were discussed and analyzed respectively in the direction of parallel to assembly slab seams and perpendicular to the slab seams.It is shown that,under the floor lateral-load corresponding to 7 degree rare earthquake,the kind of ACF is still in elastic phase.The service behavior of the assembly composite floor system is similar to a deep beam when the floor is loaded in the direction parallel to slab seams.While in the direction perpendicular to slab seams,it presents a state of bending for each assembly units respectively,The integrity behavior of the ACF in the direction parallel to slab seams is better than that in the direction perpendicular to the slab seams.关键词
