| 摘 要： | 介绍了采用在连梁两侧用螺栓固定钢板的方法加固连梁后,钢板与钢筋混凝土连梁组合协同受力、滑移分析,建立了考虑滑移效应的钢板与钢筋混凝土连梁组合协同作用下截面内力关系表达式及基于变形协调的滑移位移方程.结果表明:这些方程是建立理论模型,确定加固后连梁强度、变形的基础.

| Abstract: | This paper presents composite internal force and slip analysis between steel plate and reinforced concrete coupling beam which is strengthened by bolted side steel plates.Based on equilibrium and deformation compatibility conditions,the equations of internal force and slip displacement are developed with consideration of slip effect,these equations are foundations of building theoretical model to calculate strength and deformation of strengthened coupling beams. |

| Keywords: | coupling beam strengthening slip mechanics analysis |
