一种基于遗传算法的承重-双向抗震综合支吊架优化设计方法与系统

本发明公开了一种基于遗传算法的承重‑双向抗震综合支吊架优化设计方法与系统，属于建筑机电工程支吊架设计技术领域。承重‑双向抗震综合支吊架包括横担槽钢、竖向槽钢以及侧向和纵向抗震斜撑，横担槽钢与竖向槽钢刚接，抗震斜撑两端铰接。方法包括以下步骤：从BIM提取管线信息，计算重力荷载和双向地震作用；建立OpenSees的有限元分析模型，梁柱单元模拟横担和竖向槽钢，桁架单元模拟支撑；定义含双向地震组合的荷载工况并分析内力；在MATLAB中采用遗传算法，以侧向、纵向抗震斜撑角度为优化变量，以双向地震下最大应力比最小为目标，迭代时由MATLAB自动生成OpenSees输入文件并调用分析，获取应力，直至找到最优角度；若不满足约束则调整截面并重复建立OpenSees模型。
