摘　　要：本文对9根钢—混凝土组合梁进行了竖向加载试验,测出了该组合梁的极限荷载、钢与混凝土界面的相对滑移分布以及荷载-挠度曲线,并由此提出了根据钢与混凝土应力-应变关系,考虑钢与混凝土界面相对滑移的组合梁非线性性能分析方法,进而求解了竖向集中荷载作用下组合梁的极限荷载、钢与混凝土界面的相对滑移分布以及荷载-挠度曲线等非线性参数,通过试验对比,表明本方法分析结果与试验吻合较好.The experiment of vertical loads has been conducted on 9 steel-concrete combined beams,and the limit load,load-deflection and the distribution of relative interface slippage of the beams have been tested.From this,according to the stress-strain relationships of steel and concrete,the analysis method of nonlinear property has been presented considering the relative slippage between the steel and the concrete.The nonlinear parameters have been solved of the combined beams subjected to the vertical concentrating load.The results,when compared with the experiment,indicate that this analysis method advanced in this paper may be more coincide.
