The coupling beam work as an important component in coupled shear walls, the strength,stiffness and deformation properties of which have great influence on the seismic performance of shear walls, the steel plate reinforced concrete coupling beams have the advantages as follows: simplify the constructional details, make the construction convenient and reliable performance [1][2]. The numerical simulation model in this paper is a coupled shear wall connected by steel plate reinforced concrete coupling beams in reference [3], and the loading mode is the same as the reference [4] . The relative stiffness effect was explored by study the internal force and displacement of the model with changing the stiffness of the coupling beams and the shear walls while the span-depth ratio is stable .The study will provide a reference for the numerical simulation of the finite element simulation analysis of the coupling beams and the steel reinforced concrete structures.

This study investigates an innovative method based on low yield steel plate shear walls for seismic retrofitting of existing reinforced concrete (R/C) structures. A simplified numerical model of steel shear panels is developed for global analyses of multi-story R/C frames. The seismic performance of a non-ductile five-story R/C frame retrofitted with steel plate shear walls is evaluated in terms of drift control and energy dissipation capacity using nonlinear dynamic analyses. The results obtained by the application of two different story-wise distributions of steel plates are compared. In case of retrofitted frames a considerable decrease of the maximum top displacements is registered and the energy dissipated by the primary structural elements is significantly reduced for severe seismic actions. The energy dissipation concentrates in the steel panels, reducing the plastic demand on the structural members, along with the potential for structural damage. The different story-wise distributions of the steel panels change the damage distribution throughout the frame. The uniform arrangement of the steel panel thickness along the height of the frame causes a concentration of damage in the columns of the first story. In case of steel panel distribution proportional to story shear, the energy dissipation results more uniform over the height of the frame and a significant decrease of damage is registered for the columns of all the storeys.

Nonlinear Finite Element Model

As a new alternative design, plate-reinforced composite (PRC) coupling beam achieves enhanced strength and ductility by embedding a vertical steel plate into a conventionally reinforced concrete (RC) coupling beam. Based on a nonlinear finite element model developed in the authors’ previous study, a parametric study presented in this paper has been carried out to investigate the influence of several key parameters on the overall performance of PRC coupling beams. The effects of steel plate geometry, span-to-depth ratio of beams, and steel reinforcement ratios at beam spans and in wall regions are quantified. It is found that the anchorage length of the steel plate is primarily controlled by the span-to-depth ratio of the beam. Based on the numerical results, a design curve is proposed for determining the anchorage length of the steel plate. The load-carrying capacity of short PRC coupling beams with high steel ratio is found to be controlled by the steel ratio of wall piers. The maximum shear stress of PRC coupling beams should be limited to 15 MPa.
