| 摘 要： | 对于二根形心主惯性轴惯性矩相差较大的非对称截面梁，若其发生斜弯曲，哪怕荷载与截面形心主轴只有较小的偏角，也将对梁的强度、刚度极为不利．本文以角钢为肢件Ｚ形截面格构式檩条的截面设计为例，提出了一种怎样使其发生平面弯曲的截面设计方法。

| Abstract: | Strength and rigidity of beams will be effected adversely because of the beamswith nonsymmetric section and principal inertia difference at the principal axis of inertia atthe centroid being skewed, or the load vectors on the beams deviating small from the principal axis of centroid. For the beams bent on plane, a design method of the section is introduced based on the lattice purlin with Z style section consisting of anagle steels. |
