Analysis and Application of Shock Absorption Measures for High-rise Inpatient Building of a Hospital in High Intensity Fortification Area

A proposed 22-storey hospital building is located in an area with 8-degree seismic fortification and is a reinforced concrete frame-shear wall structure. Through the establishment of structural model, calculation and comparative analysis are carried out by using ETBAS and PERFORM-3D software. The viscous damping wall is used for energy dissipation and damping, and the optimal damping scheme is determined by multi round time history analysis and optimal adjustment of the number and location of dampers.
