| 摘 要： | 通过对钢-混凝土之间应变差的计算分析,求解组合梁负弯矩区的开裂弯矩,该方法考虑了钢梁和混凝土之间剪切滑移的影响,能够更准确的控制混凝土的开裂,并对计算结果与试验结果进行比较,证明这种计算方法是可行的。

| Abstract: | Solving the cracking moment in negative moment area of the Composite beam by analyzing the strain difference between the steel beam and the concrete. The influence of shear slip between the steel beam and the concrete was considered to control cracks of the concrete more accurately. Verifying the feasibility of the approach which was put forward in the paper by comparing caculation results and experimental results . |
