本文就工业与民用建筑中常用的平行弦普通钢屋架腹杆体系的优化问题进行探讨。文中运用结构优化理论的力学准则设计满应力原理的应力比法,探讨腹杆体系的优化方法和优化程序的编制,并按四种跨度对五种腹杆体系进行了迭代计算,经比较选优,定量的确定出不同跨度下的最优腹杆体系,供研究、设计人员参考。
This paper discusses the optimization of the common steel stringer roof web systems commonly used in industrial and civil buildings. In this paper, the stress ratio method of the full stress principle is designed by using the mechanical criteria of structural optimization theory. The optimization method of the webbing system and the preparation of the optimization program are discussed. Five kinds of web systems are calculated iteratively according to the four spans and compared and selected. Quantitatively determine the optimum web system under different spans for research and design personnel reference.
