实心截面梁剪切弯曲剪应力的计算

An Approximate Calculation of Shear Stress for a Solid Beam Subjected to Shear Beanding

提出构造剪应力因式函数的凑应力法.这种方法可以解决菱形、六边形等侧边不光滑的多边形和其它一些侧边不光滑截面的弯曲剪应力近似计算问题.将它与扩充的儒拉夫斯基公式合用,可较好地解决常见实心截面梁的此类问题.

This paper affords a semi-inverse method of stress which should be given factor functions of shear stress at first.By using this method, the problem of calculating shear stress for shear bending can be solved approximately for rhomb, hexagon and other polygons and sections whose lateral sides are not smooth boundarics.Togcthcr with gener- alized formula of Rulavsky, the similar problem of solid beams of common sections can be solved by better appoximate calculation. Furthcrmorc, for somw sections, the accurate rc- sults can be obtained.
