采用新型连接墙板的动车检查库侧向刚度研究OACHSSCD

Taking the high-speed railway EMU inspection depot as the research object,a new type of splint external node is used to connect the autoclaved aerated concrete wallboard(ALC panel)with the main rigid frame,and the influence of the wallplate on the lateral movement stiffness in the plane of the rigid frame is studied.Firstly,according to the existing test results of hook head bolt plug joints,finite element simulation is carried out to verify the effectiveness of the numerical analysis method in the study of joint performance.Then,a new type of splint external node is used,and the single-span rigid frame structure model that coincides with the longitudinal span of the EMU inspection depot is selected to install the ALC plate,and the finite element numerical quasi-static test is carried out to study the performance of the new type of joint and plate synergistic force,and the in-fluence of different loading modes and hanging plate forms on the in-plane lateral movement stiffness of the EMU inspection depot is studied.The results show that the new splint external node is suitable for the EMU inspection depot,and the ALC wall panel connected by the node has a certain influence on the in-plane lateral shift stiffness of the structure.
