摘要:
采用遗传算法和拟满应力法,以结构总质量为目标函数,杆件截面积为离散变量,对某带内树状支承柱单层球壳实际工程进行优化分析.通过在强度、杆件稳定和刚度等约束条件下,对优化结果的比较分析及对优化后的球壳结构的几何非线性全过程整体稳定性分析,使设计方案更加经济合理.算例结果表明:刚度条件对球壳结构优化起控制作用,杆件稳定和结构整体稳定性不可忽视;对带内树状支承柱单层球壳结构,要使结构设计方案经济合理,进行优化分析和方案比较是必要的.
Abstract:
Using genetic algorithm and imitative full-stress method, taking total mass of the structure as objective function and the cross-sectional area of the elements as discrete variable, the optimization analysis of a single-layer spherical reticulated shell with internal tree columns was carried out. Through the comparative analysis of the optimal solutions under constraint conditions such as strength of member, stability of member and stiffness of structure, as well as the geometrically nonlinear whole process overall stability analysis for the optimized spherical shell, the final design scheme was more economical and reasonable. The results indicate that the stiffness condition plays a controlling role on the optimization of spherical shell, stability of member and overall stability of structure can not be ignored. In order to make the design more economical and reasonable for the single-layer spherical reticulated shell with internal tree columns, optimal analysis and scheme comparison are necessary.
