大跨度桥梁结构地震反应分析的研究进展

Development of earthquake response analysis for long-span bridges

简要叙述了大跨度桥梁结构地震反应分析研究中的多点激振效应、反应分析方法、土—结构的相互作用以及结构的非线性性能问题及发展动态,以期对大跨度桥梁进行正确的地震反应分析,从而提高其抗震能力。

This paper has briefly introduced the new development of earthquake respond analysis research on long-span bridge structure, including the multi-spot excitation effect, the response analysis method, the earth-structure mutual interaction and the non-linear structure performance. In the hope of getting correct earthquake response analysis of long-span bridge, so as to improve its anti-seismic power.
