| 中文摘要: |
| 本文总结了钢-混凝土组合梁剪跨区内均匀配置柔性剪力连接件数量的局限性,分析了基于塑性理论的可变荷载或偶然荷载作用下组合连续梁桥剪跨区交界面的剪力作用机理,认为组合连续梁桥的剪力连接件配置数量和方式应依据剪跨区重叠段的剪力上限值确定,弥补了相关规范的不足。 |
| 英文摘要: |
| This paper summarizes the defect of uniform flexible shear connectors within per shear-span district in composite steel-concrete beams. Based on the plasticity theory, this paper analyzes the mechanism of shear effect on the interface of composite steel-concrete continuous bridges under variable loads or accidental loads, and considers the allocation quantities and modes of flexible shear connectors in composite steel-concrete continuous bridges should be decided by the upper limit shearing force of the repeat shear-span districts, which makes up for the defect of related standards. |
