Abstract：To study the seismic performance of assembled composite beam-precast column concrete frame structures with rebars lapping in pressed sleeve, quasi-static tests on two 1/2-scale assembled frame specimens with two story and two span were carried out for the failure modes, deformation capacity, load capacity and so on. The test results indicate that both the specimen designed as “strong column-weak beam” and the specimen designed as “strong beam-weak column” can achieve the expected failure modes. The lateral load-displacement hysteresis curves of the specimens are rounded; the minimum inter-story drift ratios of two specimens are 1/29 and 1/31, respectively, all the inter-story displacement ductility factors are greater than 4.0, indicating that the specimens have good ductility; the pressed sleeves can transfer the tensile and compressive force of rebars effectively; the non-linear analysis results of specimens using the finite element software MSC.MARC agree well with the experimental results, and the pushover analysis results show that the horizontal force-displacement curve of assembled specimen KJ1 is basically consistent with that of cast-in-place frame. The seismic behavior of assembled frames with rebars spliced by mechanical connection can meet the requirements in current codes, and the internal force, deformation and bearing capacity can be calculated according to the cast-in-place frame.
