| 摘 要： | 实验表明在竖向集中荷载作用下 ,布置单排栓钉的钢 混凝土组合梁的混凝土翼板常常出现纵向开裂。从而导致混凝土翼板与钢梁的连接作用大大降低 ,致使构件达不到设计承载力而破坏。作者从理论上分析了混凝土翼板纵向开裂的原因 ,推导了纵向开裂弯矩的计算公式 ,提出了避免出现纵向开裂措施。

| Abstract: | It is shown during experiments that longitudinal cracking always exits in the steel concrete composite beams with single line studs.For this reason,the connection between steel beam and concrete flange would reduce greatly,so the member could not reach the design point of the bearing capacity.In the paper,by studying the mechanisms of longitudinal cracking,calculating formulas of longitudinal cracking moment are derived,and methods of avoiding longitudinal cracking are put forward. \ |
