摘要
在组合梁结构中,可拆卸抗剪连接件起到承担钢梁和混凝土板之间剪力传递的作用。在组合梁破坏或达到服役期后,通过更换可拆卸抗剪连接件可实现快速恢复结构正常使用功能。可拆卸抗剪连接件是未来组合桥梁和建筑实现可持续发展的一种有力途径。对可拆卸抗剪连接件的类型、破坏模式、抗剪承载力、刚度和延性进行了综述,并提出了目前可拆卸抗剪连接件存在的问题,最后对未来可拆卸抗剪连接件研究进行了展望。
In the composite beam structure,the demountable shear connectors play a role in the shear transfer between the steel beam and the concrete slab.The composite beam structure can achieve rapid replacement and restore the normal use function of the structure after damage or service period by replacing the demountable shear connectors.Demountable shear connectors are considered to be an effective solution for the sustainable development of composite bridges and buildings in the future.The types,failure modes,shear bearing capacity,stiffness and ductility of demountable shear connectors were reviewed,and the existing problems of demountable shear connectors and the prospect of future research on demountable shear connectors were proposed.
