Experimental and shear bearing capacity studies of the assembled composite wall with bolted connections

摘要

To realize the dry connection of an assembled composite wall structure, a bolted connection based on the horizontal joint of an assembled composite wall is proposed. Five specimens were designed under monotonic loading. The failure modes, the seismic performance of the specimens, and the strains and slip of the connectors were studied. The plate thickness and the high-strength bolts diameter are the key points of research. Moreover, the finite element model for experiment is also established, and the parameters are analyzed based on the numerical models. The results of the experiments and the simulations show that the bolted connection is feasible and the specimens have good deformation capacity. Increasing the plate thickness can improve the bearing capacity of the specimens. Finally, the formula for the shear bearing capacity of the specimen is obtained.
