| 摘 要： | 结合现有规范及实验数据,探讨了节段预制拼装桥梁接缝剪切强度的计算方法,提出一种包含混凝土抗剪强度、正应力抗剪强度增量以及破坏截面摩擦力三部分的抗剪强度计算方法。新的计算公式物理意义明确、概念清楚,且与实际测量值具有较好的吻合度,对节段预制拼装桥梁接缝处剪切强度的计算具有参考借鉴作用。 |
| 关 键 词： | 节段预制拼装桥梁 剪切强度 混凝土抗剪强度 正应力抗剪强度增量 破坏截面摩擦力 |
Discussion on Shear Strength of Joint of Segmental Precast Assembled Bridge |
|
| Abstract: | Combined with existing codes and experimental data,the calculation method for shear strength of joint of segmental precast assembled bridge is discussed and a method is proposed which includes shear strength of concrete,increment of normal stress shear strength and damage section friction.The new formula has definite physical significance,clear concept and great goodness of fit with practical measured value,providing references for calculation of shear strength of joint of segmental precast assembled bridge |
| Keywords: | Segmental precast assembled bridge Shear strength Shear strength of concrete Increment of normal stress shear strength Damage section friction |
