基于部分装配式的隔震地铁车站结构性能研究
Seismic Performance of Metro Station Structures Based on Partial Prefabrication
摘要
Abstract
Given that the internal components such as middle columns,middle plates,and longitudinal beams are the weak points in the seismic performance of double-layer metro station structures,a new metro station structure with external cast-in-place and internal prefabricated components,which could be replaced after an earthquake,was proposed.A three-dimensional refined finite element model con-sidering component prefabrication and seismic isolation bearings was established to analyze the seismic performance of the new underground station structure.The results showed that when the input peak acceleration was less than 0.2g,the inter-story drift angle of the station structure with external cast-in-place and internal prefabricated components fully complied with the code-prescribed elastoplastic lim-its.The seismic damage at the longitudinal beams,middle plates,and middle columns of the new sta-tion structure was significantly reduced compared with fully cast-in-place station structures,and the seismic damage at the contact part between the middle plate and the middle column base was alleviat-ed.The bending moment amplitude in the top-bottom plate sections and side walls of the new station structure slightly increased.On the whole,the new design method with external cast-in-place and in-ternal prefabricated components can effectively improve the overall seismic performance of under-ground metro structures and their rapid post-earthquake repair capabilities.关键词
