两端铰支跨内受均匀横向剪力的压缩柱梁弯曲分析

Bending Analysis of Pressing Column-beam with Rotational Constrained at Both Ends and Uniformity Transverse Force

研究了两端铰支、跨内受均匀横向剪力作用的压缩柱梁弯曲特性,根据梁的挠曲线微分方程和边界条件,推导出了柱梁的挠度和弯矩方程,分析了轴向压力对挠度和弯矩的影响,提供了最大挠度和弯矩的近似计算公式。与理论计算结果对比表明,近似计算公式精度较高,可供工程设计使用。

The bending characteristics of pressing column-beam with rotational constrained at both ends and uniformity transverse force were studied. According to the deflection differential equation and boundary conditions, the equations of deflection and moment were deduced, the effect of axial direction pressing force on deflection and moment were discussed, and the approximate calculation formulas and results for max deflection and moment were presented and compared.
