四柱支承网架支点位置的优选
摘要
本文以杆件截面积、网架高度和支承点位置为设计变量
以结构重量为目标函数研究了四柱支承网架支点位置的优选.通过大量计算
文末还给出了四柱支承网架的最优悬挑长度、最优高度等参数.
Abstract
This paper studies the optimization on the position of bearing-points in space trusses supported by four columns
taking the cross-sectionalareas of members
the positions of bearing-points and heights of space trusses as the design variables
and the weight of structures as the objective function.After a lot of calculation
the parameters of optimal cantilever lengths and heights of space trusses supported by four columns are presented.
