| 摘 要： | 从已有的正弯矩试验出发,参考钢结构设计规范中组合梁理论,给出正弯矩和负弯矩塑性分析承载力公式,正弯矩理论值与试验值吻合,负弯矩理论值与试验值相比误差较大,因此提出简化的负弯矩计算公式,并与试验对比,计算值与试验值吻合,并指出采用钢结构规范的完全抗剪的负弯矩承载力公式计算槽钢加固悬臂梁的局限性。

| Abstract: | From the bending tests done before and according to the theories of composite beams in the Steel Structure Design Code,the paper suggests the formula for calculating the load capacity of the beam reinforced by channel steel under positive moment and negative moment by plastic analysis.Calculated positive moments are well fit for tests results,but calculated negative moments have great deviation.So the paper suggests a simplified formula for calculating the negative moment,and the calculated results by this ... |
