Comparison of seismic reduction schemes for frame structures under frequent earthquakes

In recent years, viscous energy dissipation wall is widely used in China. In the case of a 5-story frame structure, the combination of viscous damping wall (VDW), buckling restrained brace (BRB) and (VDW + BRB) is used for seismic design. Under frequent earthquakes, (VDW + BRB) scheme has the best damping effect, which can effectively reduce the response of superstructure and greatly improve the seismic safety of building structures.
