Abstract: This study investigated the seismic performance of the assembled local reactive powder concrete beam-column joints.Four full-scale assembled local reactive powder concrete beam-column joints and one cast-in-place contrast joint were tested under cyclic load reversals.The failure modes of each joint can be obtained through experiments,and can be compared with cast-in-place joints to verify whether the seismic indexes such as hysteresis performance,energy dissipation capacity,stiffness degradation and deformation capacity of local reactive powder concrete beam-column joints can meet the requirements.The test results show that the bearing capacity of PC1 joints is 9.5%~9.7% higher than that of XJ joints,and the bearing capacity of PC2 joints is 19.1%~20.8% higher than that of XJ joints.It can be seen from the failure mode that RPC can significantly improve the crack resistance of columns and beams and reduce the damage degree of the joint area.Comparing XJ,PC3 and PC4 joints,it can be found that pouring RPC in the joint area can not only improve the seismic performance of the joint,but also reduce the density of stirrups in the joint area.Finally,on the basis of the experiment,the finite element analysis model of PC1 and PC2 beam-column joints of local reactive powder concrete is established,and the calculation are in good agreement with the experimental results.Combined with the calculation of the finite element,it provides suggestions for the design of prefabricated local reactive powder concrete beam-column joints.
