为了提高结构的抗震性能,可以从结构自身的动力特性着手,在明确了不同结构在地震作用下的响应特性的基础上,通过对结构进行合理调整,使得结构在地震作用下的内力分布达到较为合理的状态。通过对一座拱桥结构体系进行地震响应分析,探讨了伸缩缝和固定墩的设置位置对结构地震响应的影响。分析研究显示,合理选择伸缩缝和固定墩的设置位置,可以显著改善全桥结构的抗震性能。
In order to improve the seismic performance of the structure, we can start from the dynamic characteristics of the structure itself. Based on the clear response characteristics of the different structures under the earthquake, the internal force distribution of the structure under the action of the earthquake can be more reasonable by adjusting the structure reasonably Reasonable status. Through the seismic response analysis of an arch bridge structural system, the influence of the location of the expansion joint and the fixed pier on the seismic response of the structure is discussed. Analysis and research shows that the reasonable choice of the location of expansion joint and fixed pier can significantly improve the seismic performance of full-bridge structure.
