Abstract:Four groups of experimental tests were conducted with T shaped beam to column connections under monotonic and reversed cyclic loading. The failure modes, moment rotation curves, moment capacity, ductility and energy dissipation properties were obtained, and the effect of bolt row and self tapping screw reinforcement on the lateral performance of the connection were studied. The results show that the cracks on traditional bolted connections occur early with rapid development. The strength and ductility, especially the strength, increases with the increase of bolt row. The self tapping screw reduces and delays wood splitting, which enhances the ductility and seismic performance of the connections.
