摘　　要：为研究焊接钢榫卯连接装配柱的可靠性,对不同钢板厚度的2个装配柱和1个现浇柱进行低周反复试验对比,分析试件的破坏形态、骨架曲线、耗能及刚度退化等。对不同轴压比和剪跨比的装配柱进行数值模拟分析,研究轴压比及剪跨比对装配柱抗震性能的影响。结果表明:装配柱延性及耗能均不低于现浇柱,抗震性能良好;钢板厚度对装配柱抗震性能影响较小;轴压比和剪跨比对装配柱承载力、耗能、刚度退化等抗震性能指标影响显著。In order to study the reliability of welded steel mortise and tenon joint assembled columns,a low-cycle reversed test was conducted on two assembled columns and one cast-in-place column with different steel plate thicknesses.The failure form,skeleton curve,energy consumption and stiffness degradation of the specimen were analyzed.The numerical simulation analysis of the assembled columns under different axial compression ratios and shear span ratios was conducted to study the influence of axial compression ratio and shear span ratio on the seismic performance of the assembled columns.Results showed that the ductility and energy dissipation of the assembled columns were not lower than that of the cast-in-place columns,and the seismic performance was good.The thickness of steel plate had little effect on the seismic peformance of assembled columns.Axial compression ratio and shear span ratio had a significant impact on bearing capacity,energy consumption,stiffness degradation and other seismic performance indicators.
