Bidirectional seismic response of assembled monolithic subway station-aboveground structure system under artificial bedrock ground motions

Underground Space
Assembled monolithic subway station partly synthesizes the advantages of cast-in-place and precast subway stations. However, the related seismic response analysis considering the influences of vertical ground motion and aboveground structure is still ...
