Study Status of Steel-Bamboo Composite Slabs

Abstract

At present, the development and application of new building structures are paid widely attention. In order to promote light-weight building slabs, different sections of steel-bamboo composite slabs are presented in this paper. Sandwiching thin-walled C-shaped steel or profiled steel sheet between two bamboo woods and bonding them with adhesive, a variety of different forms of steel-bamboo composite slabs are designed. For the C-shaped steel composite slabs, the reinforcement of self-tapping screws can effectively constraint interface slip between steel and bamboo plywood. It can also overcome the shortcoming of buckling which easily happen on C-shaped steel, ultimately, making the slabs have high stiffness and bearing capacity. The composite slabs with profiled steel sheets as the core part are strengthened by self-tapping screws and edge panels. And the global stability, deflection capacity and ductility performance of composite floors are significantly improved. Experimental results show that the reasonably combined composite slabs which have good combined effects, large carrying capacity and stiffness, can be used as architectural floors.
