摘要/Abstract

摘要： 考虑钢梁与混凝土板之间的滑移,对钢-混简支结合梁的基本动力特性及移动荷载作用下的动力响应进行了试验研究,并将试验结果与理论分析结果及数值分析结果进行了对比分析,结果吻合良好。分析结果表明:由于柔性抗剪连接件的存在,在外荷载作用下结合梁中钢梁与混凝土板之间发生相对滑移,对结合梁的动力响应产生显著影响。

Abstract: Considering the slip between steel girder and concrete slab, experiments of fundamental dynamic characteristics and dynamic response of steel-concrete composite beam under moving load are carried out. Then comparative analyses between the experimental, theoretical and numerical results are conducted, showing good agreement. The results show that due to the flexible shear connectors, the relative slip occurs between the steel girder and concrete slab of the composite beams under external loads, which significantly influences the dynamic response of the composite beams.

Key words: civil engineering, steel-concrete composite beam, interface slip, dynamic response, moving loads
