| 摘 要： | 为了考察钢-混凝土组合桥面板的整体工作性能，对1块简支钢-混凝土组合桥面板进行了试验，探讨了开孔钢板型剪力连接件的工作性能和混凝土中添加钢纤维的增强作用．在试验结果的基础上，引入混凝土和钢材的本构关系，并考虑钢纤维和贯通钢筋的影响，对试验进行了理论分析．结果表明：界面滑移出现在破坏阶段。说明此种剪力连接件能保证桥面板的整体工作性能。

| Abstract: | An experiment was conducted on a simply supported steel-concrete composite deck to investigate the working performance of steel-concrete composite decks. The behavior of a poffobond strip shear connector and the reinforcement effect of steel fiber on concrete were investigated. Based on the experimental results, a theoretical analysis was conducted by taking the stress-strain relation of concrete and steel and the effects of steel fiber and transverse steel bars through the holes of porfobond strips into account. The result shows that no slip occurs between steel bars and concrete before the failure of the structure and thus this type of shear connectors can guarantee the integral working performance of a steelconcrete composite deck. |
