Time-History Analysis of Seismic Performance of Metro Station by Top-Down Boring with Cast-In Situ Arch

Taken the Dawanglu station of Beijing metro line 14 as engineering background, the seismic performance of metro station by top-down boring with cast-in-situ arch under rare earthquake action (E3) is researched. A three-dimensional dynamic model is established by using the finite element program MIDAS/GTS. Through the time-history analysis method, the displacement response of the main structure of metro station is obtained. The storey relative displacement and storey drift angle of the main structure are mainly analyzed. Numerical results show that under rare earthquake action, metro station structure can satisfy the requirements of the seismic performance, and can be regarded as a valuable reference for the design.
