Abstract：
ANSYS finite element analysis software was used to establish coupling shear wall structure model for plate-supported dual coupling beam and plate-supported single coupling beam and horizontal load was applied on the structure top to study their mechanical performance under horizontal load. This paper analyzed coupling beam, internal force of connecting wall, maximum displacement on top, failure form, ultimate bearing capacity of structure and ductility of plate-supported dual coupling beam and compared these characteristics with those of plate-supported single coupling beam. This study found that plate-supported dual coupling beam could effectively reduce the shearing force and bending moment of coupling beam without affecting the transmission of horizontal force and has significant effect on improvement of forces of connection wall; compared with plate-supported single coupling beam, plate-supported dual coupling beam has somewhat lower ultimate bearing capacity and lateral force resistance, but obviously larger displacement flexibility. Engineering practices were analyzed to verify the conclusion of finite element analysis and to confirm the validity of dual coupling beam structure in engineering application, providing references for structural design in the future.
