In order to investigate the seismic performance of connection between steel coupling beam and steel-concrete composite shear wall，four 1：4 scaled specimens considering the influences of beam span and axial load ratio were designed, fabricated and tested subjected to constant wall axial load and vertical cyclic reversed load at steel beam end. The load transfer mechanism and ultimate failure patterns of the specimens were observed and compared. The load-deformation hysteretic behavior, deformation capacity and stiffness degradation characteristics were discussed. Test results indicate that the bolted endplate connection can provide adequate load carrying, deformation and energy dissipation capacities. Strength and stiffness degradations are not obvious. However the internal connection of embedded steel shape at boundary elements to the web of wall needs to be enhanced. When wall axial load ratio is increased severer concrete cracking and spalling can be developed at the beam-wall connection region while peak load and displacement ductility can be slightly increased. When the coupling beam span is increased, the connection region can dissipate more energy causing severer concrete crushing. The finite element analysis was conducted to simulate the load -deformation backbone curves of the specimens. The simulated and experimental results agree very well. [ABSTRACT FROM AUTHOR]
