Seismic Performance and Strength Prediction of Precast RC Shear Walls with Openings for Cavity Structures Crossing Underground Utility Tunnels

Additional loads from new buildings spanning existing underground utility tunnels, together with seismic action, may induce uneven settlement and structural damage in tunnel systems. To mitigate this risk, a precast cavity structure is proposed to replace the soil above the tunnel, isolating load transfer and controlli...
