摘　　要：为研究钢板-混凝土组合梁的受力性能,对2片带肋钢板-混凝土组合梁和1片普通钢筋混凝土梁进行了负弯矩区段的试验研究分析以及极限抗弯承载力计算方法的探索。试验表明,钢板-混凝土组合梁在抗弯承载力、刚度上表现良好。提出的钢板-混凝土组合梁极限抗弯承载力弹性-塑性相结合的计算方法,计算值与试验值较吻和。To research the mechanical performance of steel plate-concrete composite beams（SPCC）, 2 ribbed steel plate-concrete composite beams and 1 reinforced concrete beam is studied through the experiment in negative bending moment area and is explored by calculating method of ultimate flexural capacity. Experiments show that the steel plate-concrete composite beams have good performance on flexural bearing capacity and rigidity. The calculating method of elastic-plastic ultimate flexural capacity and the results of the calculating method is found to be in good agreement with the experimental results.
