摘要
考虑了钢梁腹部钢筋混凝土对组合梁抗剪性能的影响,给出了部分外包简支组合梁弹性理论计算时的剪应力分析方法,对塑性抗剪承载力的计算引入了钢骨混凝土梁的抗剪承载力计算公式,结合试验进行对比,给出了部分外包简支组合梁的塑性抗剪承载力公式,可以为实际工程应用提供参考。
Analysis method of shear stress based on elastic theory is presented for partially encased composite beam, considering the influences on the sheafing behavior brought by the reinforced concrete between the flanges of the steel. Referring to formula for shearing capacity of steel reinforced concrete beam and comparison of test results, author points out formula for plastic sheafing capacity of partially encased composite beam. The results could supply references for the application in civil engineering.
