Experimental Seismic Performance Research on a New Assembled Monolithic Column Joints

11766,11767,2832,11768,11769

A new assembled monolithic column joints were put forwards: local outsourcing steel tube column joints. Through four full-scale specimens under cyclic loading contrast test, the failure form, hysteresis curve and skeleton curve were studied. The test results show that: the overall performance of outsourcing steel tubal column joint is better than other tradition joints, for without drawing or detachment phenomenon; Under the same conditions, node hysteresis curve and skeleton curve are similar to cast-in-site RC columns. These joints also have good ductility and energy dissipation capacity. Rupture of the test’s samples belongs to large eccentric compression failure, which ductility is better. The research results can provide the reference of theory research and practical engineering application connected to the assembled monolithic column.
