Abstract:Couple shear wall structures are well known for their lateral stability and have a promising future in large complex tall structures.Coupling beam dampers are the key components of coupled shear wall structures.In this manuscript,metallic in-plane yielding coupling beam damper with four types of proration and different pore areas are analyzed by the Finite Element Method.It is found that the hourglass-shaped poring coupling beam damper has superior hysteretic behavior and higher load-carrying capacity compared with other types of poring dampers.In addition,the optimized proration parameters are further obtained by using Kriging surrogate model,which maximize the carrying load-capacity and enhance hysteretic behavior of the hourglass-shaped coupling beam damper.
