Seismic Analysis of L-Shaped Irregular Plane Frame Structure with Viscous Dampers

Abstract:

L-shaped plane structure in the common buildings cannot meet seismic requirements because of significant torsion. According to the analysis of the vibration characteristics, structural deformation and base shear of irregular L-shaped plane structure under frequent and rare earthquake, four arrangement plans of viscous dampers are proposed to adjust the stiffness of the structure. The layout principles of viscous dampers are obtained by comparing effects of different arrangements such as in the periphery, in the short sides, in the long sides and in both short and long sides.
