The Research On Mechanics Properities Of Steel Bamboo Composite Slabs

Bamboo resources is very rich in China. Bamboo species and area is about one-fouth,bamboo production is about one-third of the world. It occupies the head of the variouscountries. As a kind of fast-grown forest resources, its superior property is already concernednow and is used in some fields. But there is some distance for application in domain of civilengineering. The main reason is that there is no method of simplicity and accuracy accepted byengineering.The paper firstly introduces the mechanical testing of plybamboo. The deflection under alllevels of loads is tested and the elasticity of flexure module and bending strength are gotten bytentative data.Secondly composite slab experiment is discussed. Experimental parameters are thethickness of plybamboo and cold-formed steel deck. The destruction process, destruction shapeand the destruction mechanism of composite slab id discussed and the combination effect isinspected by observing stain of cold-form steel deck and plybambaoo under all levels of loads,and the limit anti- curved bearing capacity of the floor is obtained. The test result indicated thatcombination is quite reasonable, the combined effect is good, the floor has a good bearingcapacity and it can be used as floor in buildings.Test stain of cold-form steel deck and plybambaoo under all levels of loads. Study thedevelopment of deflection through experiment, discuss composite slab destruction process,destruction shape and the destruction mechanism .inspects the combination effect and obtainsthe limit anti- curved bearing capacity of the floor. The test result indicated that combination isquite reasonable, the combination effect is good, the floor has a good bearing capacity and itcan be used as floor in buildings.Finally the beating capacity and distortion formula is proposed by testing research andtheory ananlysis. The analytic result of ANSYS program, the result of theory calculation andtest are good fit and the feasibility of formula of theoretic calculation is proved. It proves thatthe element type, meshing fashion and coupling manner used in ANSYS model can be used incalculation and analysis of Steel Bamboo Composite Slabs.
