摘要
针对我国存在大量的预应力组合箱梁桥处于地震多发环境,结合某座组合箱梁桥实例,利用有限元模拟软件,根据桥梁实际状况及荷载参数,以反应谱法的原理逐步分析了该桥的抗震性能。
In view of the fact that there are a large number of pre-stressed composite box girder bridges in earthquake-prone environment in our country, this paper uses finite element simulation software to analyze the seismic performance of a composite box girder bridge step by step based on the actual situation and load parameters of the bridge and the principle of response spectrum method.
