Seismic performance of energy dissipation low reinforced concrete shear wall with shear lead dampers
Source abstract
Abstract
This paper proposes a novel energy dissipation low reinforced concrete (RC) shear wall to improve the seismic performance of the high-rise building. The novel energy dissipation low RC shear wall composes of shear wall, inner several vertical gaps and some built-in new lead dampers. In the novel shear wall, the inner lead dampers can produce a marked effect on energy dissipation and shear transmission. This paper first presents the simulation studies of lead dampers, including the simulation method and the simulation analysis. Based on the above study results, the following contents use ABAQUS software to study the seismic performances of the new energy dissipation shear wall, including the damage patterns, hysteresis curves, stiffness degradation and energy dissipation capacity. The analysis results show the proposed shear wall has well seismic performance. Meanwhile, the ductility of the proposed shear wall is higher than that of the conventional low shear wall. The bearing capacity is higher than that of the shear wall with vertical gaps. But the energy dissipation capacity decreases with the increase of the axial pressure ratio under a large axial pressure ratio. Especially, the number and the arrangement of lead dampers have an obvious effect on the seismic performance.
