| 摘 要： | 钢—混凝土组合式吊车梁支承端处于压、拉、剪复合应力状态，同时，由于施工误差，使支承端存在约束弯矩，是造成端部混凝土开裂的主要原因。本文在计算分析的基础上，提出了相应的构造处理方法。该方法对于类似钢—混凝土组合结构具有一定参考价值。 |

| Abstract: | It is the reasons of cracking in the ends of built-up crane beam,which the tension,compression,and share,as well as the eccentric moment are all acting on.On the basis of the calculating and analysis,the improve detail have been presented in this paper.These methods are good reference value to similar steel-concrete combined members,such as flitch-trussed beam,composite roof truss. |
| Keywords: | steel-concrete composite structure crane beam finite element analysis |
