Abstract

Abstract

Based on the deflection of structural components occurring at the lateral deformation of moment frames, the author proposed a new lateral resistance RBF (R-Brace Frame) system, which is capable of effectively limiting the drift of tall buildings. To evaluate internal force distribution and deformation of the RBF system, FEM program SAP2000 was used. Pushover method and capacity spectrum method were used to assess yielding mechanism of seismic performance of the structure under rare earthquake. The findings revealed that the RBF system had a major impact on improving the structure's lateral stiffness. The stiffness deterioration of the RBF system is controllable, and the seismic ductility of the structure can be guaranteed by the RBF system. The RBF system would not alter the direction of propagation of the vertical force of the initial structure. It is ideal for existing buildings for seismic retrofitting.
