| 摘 要： | 东平大桥桥面板采用钢-混凝土组合结构形式,剪力连接件采用开孔钢板,混凝土中添加钢纤维。对1片处于正弯矩区域的组合桥面板进行试验,结果表明,这种形式桥面板在使用荷载作用下结构变形小,具有较大的刚度;在疲劳荷载下,结构的刚度衰减较小;结构破坏时具有较高的承载能力,安全储备较高。

| Abstract: | The deck slab of Dongping Bridge is designed as a steel and concrete composite structure with its shear connectors used with perfobond strips and concrete added with steel fibers.In this paper,the experiment is made for a piece of the composite deck slab of the Bridge in the positive bending moment zone.The results of the experiment show that the structural deformation of the deck slab under service load is little,the slab has fairly great rigidity,the reduction of the structural rigidity of the slab under fatigue load is also little and there is still rather great load bearing capacity and safety margin at the time the slab structure fails. |
