摘要:
为了得到弯剪型悬臂柱的屈曲临界荷载,通过将横向均布荷载作用下悬臂柱的弯曲变形曲线和剪切变形曲线作为其在均布压力下的挠度曲线,用能量法推导了弯剪型悬臂柱的屈曲临界荷载计算公式.将推导的公式与弯曲型悬臂柱屈曲临界荷载公式对比,发现弯剪型公式仅比弯曲型公式多了一个无量纲修正系数,对系数进行了拟合得到了更为简便的公式.与有限元结果相比,所推导和拟合的公式精度很高,且形式简单,应用方便.
Abstract:
In order to derive the shear-flexural cantilever column buckling load formula,the energy method is used by taking the flexural deformation curve and shear deformation curve of cantilever columns under lateral uniform load as the deformation curve under uniformly distributed load.Then the result is compared between the shear-flexural cantilever column and bend cantiever bar in the paper, and one dimensionless coefficient is recognized. A more concise formula is obtained. Finite element analysis shows that the formula derived has a convenient application and high precision.
