| 摘 要： | 基于Reissner-Mindlin一阶剪切变形板理论，讨论了钢筋混凝土悬臂板在纤维增强复合材料补强情况下的弯曲及自由振动问题．采用Rayleigh-Ritz法导出了弯曲分析中的挠度和弯矩以及振动中的自振频率．数值计算结果表明，混凝土悬臂板补强后挠度减小，自振频率增大．

| Abstract: | An analytical numerical study was presented for the bending and vibration of RC cantilever plates strengthened with fiber\|reinforced polymer(FRP) strips. The analysis was based on Reissner Mindlin plates theory, considering the first order shear deformation effects. The Rayleigh Ritz method was used for determining the defections, bending moments and natural frequencies of the strengthened plate. The numerical results show that the FRP strip, bonded to the bottom of the RC cantilever plate, reduces the deflection but increases the natural frequency. |
