本文以某独柱长悬臂高架车站工程实例为分析对象,提出该类结构抗震设防性能目标,并采用有限元软件ABAQUS对该结构进行抗震模拟分析,描述了结构体系的塑性发展过程,指出罕遇地震作用下关键结构构件的塑性状态并给出相应的加强措施,同时分析了屋盖结构对整体结构计算的影响,为同类车站结构分析提供参考。
In this paper, taking a cantilever overhead crane station with a single pillar as an example, this paper presents aiming at the seismic fortification performance of this kind of structure, and uses the finite element software ABAQUS to analyze the structure aseismicly and describes the plastic development process of the structure system. The plastic state of the key structural members under the earthquake and corresponding reinforcement measures are given. At the same time, the influence of the roof structure on the overall structure calculation is analyzed, which provides reference for the structural analysis of the similar stations.
