EXPERIMENTAL STUDY ON FLEXURAL BEHAVIOR OF BAMBOO-STEEL COMPOSITE HOLLOW FLOOR SLABS
Bamboo which has the advantages of high tensile strength, light weight, high rigidity etc. is a good kind of engineering structural material. In order to widen the applied range of bamboo and implement the diversification of component materials and forms in building structures, the author forwards a new kind of bamboo-based composite slabs, which sticks bamboo plywood and profiled steel sheet together into bamboo-steel composite floor slabs by structural adhesive, and a series of experimental and theoretical studies were conducted on the new kind of composite slabs. With thicknesses of the bamboo plywood and profiled steel sheet in the core and the span of slabs as parameters, mechanical properties are tested on 6 pieces of the composite slabs. Test results reveal that the tested slabs, which provided superior bearing capacity and stiffness, performed with fine composite action; the mechanical properties can meet the requirement of building floor slabs. Moreover, this paper puts forward the calculation method for die bending rigidity and the ultimate bending bearing capacity of the composite slabs. And the computational values of the mid-span deflection and flexural capacity of slabs chime well with the experimental dates. It is proper for this kind of composite slabs to be used as structural components for its lightweight, high strength, good energysaving and recycling continues.
