Seismic Response of Cross Interchange Subway Stations in Soft Soil: Effects of Intersecting Structures and Inhomogeneous Deformation
Seismic response of cross interchange subway stations in soft soil is studied through dynamic time history analysis. The inhomogeneous deformation and internal forces of the structure are examined under moderate earthquakes, considering intersecting effects and ground motion frequency. Findings indicate that the intersecting part of two-story and three-story sections creates a rigid connection, increasing stiffness and unique deformation patterns. This leads to an abrupt distribution of internal forces and significantly affects lateral drift ratio, requiring careful consideration in seismic design. Low-frequency ground motions demonstrate distinct heterogeneity in racking deformation distribution. Insights contribute to improved seismic design of soft soil subway stations.
