可拆卸钢-混凝土组合梁的研究综述和展望
State-of-the-art review and future trends on demountable steel-concrete composite beams
摘要
Abstract
Efficient disassembly and reuse of structural components are key strategies for achieving green,low-carbon,and sustainable development in the construction sector.This paper presents a comprehensive review of recent research on demountable steel-concrete composite beams,summarizing the structural characteristics and implementation strategies of demountable shear connectors.The installation feasibility and critical factors affecting their performance are analyzed.Focusing on the steel-concrete interface,concrete slab joints,and beam-to-column connections,this study explores the interface compatibility mechanisms and load transfer paths of demountable composite beams.The multi-stage shear-slip behavior induced by demountable connectors and its influence on beam stiffness,load-carrying capacity,and seismic performance are examined.Furthermore,current design methods are insufficient for accurately evaluating the dynamic evolution of composite action and the associated interface slip demand.The ductility requirements for welded studs prescribed in Eurocode 4 may not apply to demountable shear connectors.Finally,future research priorities and directions are proposed concerning structural detailing optimization,long-term performance,interface compatibility mechanisms,and seismic design of demountable steel-concrete composite beams.关键词
