钢竹组合箱形梁抗弯性能试验
Experimental investigation on bending behavior of box section bamboo-steel composite beams
摘要
Abstract
Box section bamboo-steel composite beams consist of two pieces of cold-formed thin-wall U section steel as skeleton and four pieces of bamboo plywood on surfaces of steel with structural adhesive.Six specimens were tested to evaluate effects of bamboo plywood thicknesses,steel thicknesses,and section sizes.In order to explore the failure process,failure mechanism and bending performance,which contained bending stiffness,serviceability limit load and ultimate load,bamboo plywood strains,steel strains and deflections of beams were measured.The test results showed that overall performances of composite beams were excellent and bonding between steel and bamboo plywood was reliable.Increasing bamboo plywood thickness and section size were conducive to improve bending stiffness and ultimate load of composite beams,while ductility and ultimate load were enhanced with increase of steel thickness.The research showed the failure of composite beams had remarkable ductility characteristics and favorable security reserves,this new type composite beam could serve as bearing components in architectural engineering.关键词
