摘要:
采用2根冷弯薄壁U型钢作为箱形骨架,型钢外表面用结构胶黏剂黏结4块竹胶板,形成钢-竹组合箱形梁。以竹胶板厚度、薄壁型钢厚度及U型钢截面尺寸为控制参数,对6根组合箱形梁试件进行抗弯性能试验,测量各级荷载作用下型钢、竹胶板应变与挠度发展,分析破坏过程与破坏机制,探讨组合梁的抗弯刚度、正常使用极限荷载、承载能力极限荷载等抗弯性能。试验结果表明,组合梁整体工作性能优良,型钢与竹胶板黏结可靠,竹胶板厚度与U型钢截面尺寸的增大有利于提高组合梁的抗弯刚度与极限荷载,型钢厚度的增大有利于增强延性性能与极限荷载。研究表明,钢-竹组合箱形梁的破坏具有明显的延性特征,具有良好的安全储备,能够作为受力构件用于建筑工程。
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.
