摘要
以五层钢结构模块建筑住宅为例,探索钢结构模块建筑参数化平面多目标优化和结构智能化设计的完整链条。提出一种钢结构模块建筑参数化平面建模和设计方法;依托Rhinoceros&Grasshopper建模平台,编写Python脚本语言实现智能化结构设计;最后结合Ladybug&Honeybee建筑能耗性能模拟插件和Karamba有限元结构设计插件以及Octopus数据处理平台,基于建筑总能耗和结构用钢量2个目标分别对建筑平面不同房间长宽尺寸和结构构件尺寸进行设计和优化,生成满足结构承载力要求的Pareto最优解集,得出各参数变量与目标函数的相关性系数。
This article takes five-story steel structure modular building housing as an example to explore the complete chain of multi-objective optimization for parameterized plane and structural intelligent design.First of all,a parametric plane modeling and design method for steel structure building are proposed.Secondly,the Rhinoceros&Grasshopper modeling platform is used to write a Python script language to achieve structural intelligent design.Finally,the Ladybug&Honeybee building energy performance simulation plug-in and Karamba finite element structure are combined with Octopus data processing platform.Based on the two goals of total building energy consumption and steel consumption,the size of different rooms on the building plane and the size of structural members are designed and optimized to generate the Pareto optimal solution that meet the requirements of structural bearing capacity,and the correlation coefficients between parameter variables and the objective functions are obtained.
