摘 要: 证明了对于正多边形截面、圆形截面这样一类特殊截面梁 ,在两个相互垂直的形心主惯性平面内作用有横向外力时 ,其应力计算既可以按两相互垂直平面内弯曲的一般方法计算 ,也可以按平面弯曲计算 .由此证明了弯曲理论的严谨性和统一性 . It is proved that the stress of special section beam, such as equilateral polygon and circular section beam, can be got with common method of bending in two perpendicular planes, or in plane bending when lateral forces are acted on two perpendicular main inertial centroid planes. Bending theory is verified to be precise and unified.
