摘要：

An experimental study was performed to investigate the unbalanced moment-carrying capacity of slab-column connections reinforced with lattice shear reinforcement. Cyclic loading tests were performed on four specimens with this lattice shear reinforcement. For comparison, eight specimens reinforced with existing shear reinforcement methods (studrails, shear bands, stirrups, and no shear reinforcement) were also tested. All shear reinforcement methods were designed to enhance the unbalanced moment-carrying capacity of the slab-column connections. The test results showed that in the enhancement of the unbalanced moment-carrying capacity of slab-column connections, lattice shear reinforcement was better than the other shear reinforcement methods. Lattice shear reinforcement increased the unbalanced moment-carrying capacity of the slab-column connections by more than 1.8 times that of the specimens without shear reinforcement. All shear reinforcement methods significantly improved the deformation capacity of the slab-column connections. DOI:10.1061/(ASCE)ST.1943-541X.0000484. (C) 2012 American Society of Civil Engineers.
