Three Dimensional Seismic Response Analysis of Complicated Metro Station with Shallow Depth

Abstract:

Focusing on a complicated metro station with shallow depth, its three-dimensional calculation model was established, which includes not only the main station structure, but also includes the subsidiary structure such as the entrances and detailed structures such as the holes in the floor. The Davidenkov model was employed to simulate the nonlinear characteristics of the soil. The three-dimensional nonlinear seismic responses were analyzed. it can be shown from the calculation that: (1) the metro station structure can satisfy the demand under given seismic motion; (2) it is more important for structural concept design and structural measures design than the strength and deformation design for complicated underground structures.
