Earthquake Response and Design of Energy Dissipation for a 22 Story Apartment Building

摘要

Vibration control of a 22 story RC frame-shear wall apartment building with large aspect ratio was studied in this paper. Three vibration control plan with mild steel dampers, viscous dampers and viscoelastic dampers were proposed to control structural dynamic responses under earthquake. The dynamic responses of the structure with the proposed control schemes under earthquake excitations were investigated and their vibration control effects were compared. The numerical analysis results show that structural dynamic responses under earthquake excitations can be decreased effectively using the proposed plan. The earthquake response with viscous dampers was smaller than that with mild steel dampers and viscoelastic dampers. The shear force, drift and the acceleration of the structure with viscous dampers were 20%-40% less than the structure without any dampers for the slender structure.
