Abstract:In order to study the mechanical performance of the bottom plate of the T-ribbed composite slab(HTPKG slab)composed of assembled monolithic high ductility concrete(HDC),ribbed composite slab(PK slab)and cold-formed thin-wall steel,the static load test of four HTPKG prefabricated s lab specimens was carried out to study the stiffness and bearing capacity of HTPKG slab.The influence of span,upper flange width and web width on the compression performance and bearing capacity of HTPKG slab is analyzed,and the optimal slab type is selected.The test results show that cracks appear in the middle of the bottom span of the four components when loaded to 4.4~4.5 kN respectively,and no brittle fracture occurs until the extreme loading,indicating that the HTPKG plate has good bearing capacity and ductility characteristics.The performance of HPTKG-4 is the best.
