摘要
城市交通建设中,地铁以其快速高效的特点,发挥着越来越重要的作用。而在地铁车站结构设计中,地震工况下中板开洞对结构的影响往往考虑不足。本文通过理论分析和有限元软件建立计算模型,分析了地下车站反应位移法地震作用下结构的内力,重点从结构概念和有限元模型分析研究了地震工况下中板开洞对框架柱受力的影响,并针对性地给出不同的加强措施的建议。同时通过对比分析,为今后地铁车站精细化设计提供了一定的参考和依据。
In the construction of urban transportation,the metro has played an increasingly important role due to its rapidity and efficiency.In the structural design of subway stations,the influence of the middle slab opening to the structure under seismic conditions is often considered insufficient.In this paper,the theoretical analysis and finite element software are used to establish the calculation model,and the internal forces of the structure under the action of the seismic response of the underground station are analyzed.The structural concept and the finite element model are used to analyze the opening of the middle plate to the frame column under seismic conditions,specific suggestions for strengthening measures are given.At the same time,through comparative analysis,it provides a certain reference and basis for the refinement design of future subway stations.
