Effect of Different Types of Middle Columns on the Seismic Performance of Single-Story Subway Station Structure

In view of the seismic weak component of the single-frame-type subway station structure, the three-dimensional (3D) time-domain nonlinear finite element static-dynamic coupling analysis model of interaction between soil and subway station structure is established by, respectively, using rectangular...
