Lintel Type Damping Device for Seismic Retrofit of Shear Wall Structure

The methods for improving the seismic performance of the structure are the increasing the strength or the ductility capacity of the structure. In order to increase the strength of the shear wall structure, there are methods to increase the cross section of the structural member as like the shear wall or beam, and increase the rebar amount, but these are unreasonable in terms of design and construction. Therefore, in order to improve the seismic performance of the shear wall structure, it is reasonable to improve the ductility capacity by using the damping device. In this study, the seismic performance of shear wall structures with the lintel type damping device was analyzed. It can be seen that the energy dissipation of the damping device is greatly increased after the nonlinear behavior of the shear wall structure, thereby reducing the damage of the main structural members.
