Research on Seismic Performance of Coupling Beam and Shear Wall Nodes Based on Equivalent Reinforcement Connections
In order to study the seismic performance of coupling beam and shear wall connected by equivalent reinforcement,and to provide a basis for the connection design of assembled concrete connecting beams and shear walls.Cast-in-place and assembled beams were modeled using the finite element software WCOMD,and the damage processes of both were compared and analyzed.The result shows that without considering the expansion of the end damage of the coupling beam extending into the wall,the assembled beam is 3.98%,15.19%and 12.76%higher in yield,peak and ultimate load than the cast-in-place one,and its ductility and energy dissipation factor are increased by 3.83%and 15.84%respectively.The assembled beam without considering the end damage of the coupling beam extending into the wall is 5.97%,0.84%and 3.57%higher in yield,peak and ultimate load than the assembled one considering this situation,and its ductility and energy dissipation factor are increased by 1.07%and 23.76%respectively.It can be concluded that the method of connecting coupling beam and shear wall by using equivalent reinforcement is practical.The equivalent reinforcement area ratio,the grouting length in the assembly area and the assembly location have a large influence on the load carrying capacity of the structure.
