摘要
本文根据斜平面杆件的特点建立了扩大四弯矩方程,从而扩大了原有四弯矩方程的应用范围。应用扩大四弯矩方程可以简便地求解桁架中斜平面杆件的计算长度,并且也易于在分析中反映多种影响因素的作用。
The extended four-moment equation is established by taking account or thecharacterization of inclined-plane struts, which extended the application of the originalfour-moment equation. It is convenient to solve the effective length of various struts oftruss having inclincd-plane struts by using the extended four-moment equation. In addi-tion many influence factors is also considered by analyzing in the paper.
