Abstract:A new type of through-node of rectangular tube concrete column-SRC beam steel suitable for rapid construction is proposed. With reference to two actual building specifications, four-node test pieces were designed. Based on the pseudo-static load tests, the seismic performance of the joint specimens was discussed, and the seismic behaviors, such as failure phenomena, hysteretic behavior, stiffness, ductility and energy dissipation capacity were analyzed. The test results show that the failure mode of the joint is the compression failure of the concrete at the beam end concrete, coupled with the buckling of steel flange and finally forming a plastic hinge. The hysteresis curve of the specimen is relatively full, and the stiffness is obviously degraded. The ductility coefficient is between 2.33 and 3.8. The equivalent viscous damping coefficient is between 0.283 and 0.4. Compared with the existing nodes, the new type of joint has high rigidity and avoids the problem of difficult core concrete pouring.
