Study on Flexural Performance of Profile Steel-Continuous Spiral Stirrup Concrete Composite T-Beams
摘要
Abstract
This paper proposes a kind of profile steel-continuous spiral stirrup concrete composite T-beam.Finite element analysis and experimental studies are conducted on this composite T-beam.Compared with the spiral stirrup concrete T-beam without profile steel,the stress state,failure mechanism,and damage resistance behavior of the profile steel-concrete composite T-beam with continuous spiral stirrups are investigated under mid-span loading.The effects of concrete strength grade,steel flange width,and spiral stirrup spacing on the mechanical performance of the composite T-beam are analyzed.The results show that,compared with the spiral stirrup concrete T-beam without profile steel,the profile steel-concrete composite T-beam with continuous spiral stirrups maintains its ultimate bearing capacity even when the concrete is severely damaged.Furthermore,the ductility of the T-beam is significantly improved.Under peak loading conditions,the profile steel-concrete composite T-beam with continuous spiral stirrups exhibits superior damage resistance.关键词
