预制装配式地铁车站单榫槽式接头抗弯刚度影响因素分析
Influencing Factor Analysis of Bending Stiffness of Single Tenon Groove Joint of Subway Station Constructed with Prefabricated Elements
摘要
Abstract
The joints of metro station constructed with prefabricated elements are the weak parts in station structures. With reference to Yuanjiadian metro station on Changchun metro line 2, this paper studies the various influencing factors of joint bending stiffness of the single tenon groove joint subject to combined action of axial force and bending moment using numerical simulation method. The calculation results indicate that the bending moment at the joint is the main factor causing the decrease of the bending stiffness of the join, the increase of axial force and the grouting at the joints significantly impact the bending stiffness of the joints and the effect of the joint geometry parameters on the bending stiffness of the joint is related to axial force acting on the joint.关键词
