L形截面柱双向纯弯曲力学分析

On biaxial pure bending mechanical analysis of L-shape section column

针对L形截面柱在双向弯矩My,Mz作用下发生的双向纯弯曲耦合问题采用逆解法和应力函数方程进行了求解,并且得出I形截面柱发生双向纯弯曲耦合现象的主要原因是截面的Iyz≠0的结论。

Aiming at the biaxial pure bending coupling problems of L-shape section column under the biaxial bending moment My and Mz, the paper adopts the inverse method and the stress function equation, and concludes the main reasons for the biaxial pure bending coupling prob- lems of L-shape section column is Iyzx=0 of the section.
