Computation of coupled shear wall structure with coupling beam damper

Abstract

Coupled shear walls are effectively used in high-rise and tall buildings to resist the lateral loads induced by wind and earthquake hazards, mainly due to their ability to control lateral displacement of the structure. Coupling beams play an essential role in ensuring the stability of the structural system even when the beams fail. Therefore, the coupling beam must be designed so that the strength and stiffness can meet the working requirements of the structure. Recently, several solutions have been proposed to change the structure’s dynamic characteristics such as reducing vibrations, increasing resistance, absorbing and evenly distributing earthquake energy for the whole building. Meanwhile, energy dissipation devices have been widely applied. This paper mainly focused on the construction of the stiffness matrix of the coupling beam damper, and comparison of peak displacement of 10-story coupled shear wall with energy dissipation devices from the results of usage analysis two different calculation software. The obtained results indicate the agreement between the two calculation programs (a self-configured calculation based on the Matlab programming language platform and the other using SAP2000), so the new stiffness matrix of the element can be used to analyze a coupling beam with an energy dissipation device in coupled shear wall.
