摘要
以组合梁的模态和其在地震作用下的响应为研究目标,从理论和有限元分析两方面进行研究,互为参考;结合实例对混凝土滑移效应下刚度和动弹性模量以及组合梁的自振特性等有关问题进行了探讨,并将计算值与试验结果进行比较。结果表明,计算值与试验值吻合较好,可以为组合梁的相关设计提供参考。
Based on the vibration characteristics and the earthquake＇s response of composite beams to the seismic action by comparing and thinking over the two methods： theory reference and the finite element method; In the light of a example, the paper makes an approach to problems of the effect on stiffness with slip existing on the interface and the dynamic elastic module of concrete and self-vibration characteristics of composite beam. The results show that the calculation results are consistent with experimental results, which can provide reference for engineering application.
