Experimental Research on Seismic Performance of Rigid Joint Between Steel Beam and Concrete Wall

In recent years, steel-concrete composite structure has been widely applied in high-rise buildings of China, recent related studies mainly focus on the relative displacement between the structure layer control of the structural system under the seismic effect and structural failure type under the rare earthquake action, but there is sufficient comprehensive research on seismic weak position of the structural system (such as the joint between steel frame beam and reinforced concrete core-tube). Based on previous studies, this paper combines with the practical situation in China, carries out low-cycle reversed loading test on three specimens of rigid joints between steel beam and concrete wall, compares the bearing capacity with the seismic performance under the low-cycle reversed loading test, and this paper makes experimental research and theoretical analysis of the failure form, hysteretic curve features, rigid change, yield load, ultimate load, failure load, ductility, energy-dissipating capacity, strain distribution of key parts and forces in the joint core region of three node specimens.
