生成式智能结构设计在建筑设计投标的应用案例

Application case of building design bidding using generative intelligent structural design

投标是建筑工程设计的重要环节,其执行周期短,建筑、结构、管线等多专业配合紧密。高完成度的设计成果对提升投标成功率具有重要意义。因此,高效的建筑结构方案设计是投标阶段的关键需求。目前依赖人工的设计方法在有效的时间内完成的结构方案设计数量有限,难以很好地服务多个不同的建筑投标方案。相对而言,智能化建筑结构生成式设计方法由于学习了大量结构设计数据,进而具备强大的设计能力,可在短时间内完成与不同建筑设计配套的结构方案设计,支撑建筑设计的多方案比选。面向建筑设计投标的需求,本研究集成了建筑结构方案智能设计方法,完成了设计流程自动化,包括:结构设计图、结构分析模型、材料用量数据生成。结果表明,对于单个建筑,生成式智能化结构设计效率相比于人工设计提升近10~15倍,且能同时开展多个项目设计,智能设计的结构力学性能全部满足规范要求,且材料用量与工程师设计基本一致。

Bidding is a crucial component of a building design project,with a short execution period and strong collaboration between the various disciplines of architecture,structure,pipeline,etc.Improving the possibility of bid success is highly dependent on the quality of the design outcomes.Consequently,efficient building structural scheme design is a key requirement in the bidding stage.Currently,manual design methods are only capable of producing a limited number of structural scheme designs in an efficient amount of time,and it is difficult to effectively service many architectural schemes.In contrast,the generative intelligent structural design method has a strong design ability due to the learning of a large amount of structural design data,and can complete the structural scheme design supporting various architectural designs in a short time,supporting the comparison and selection of multiple plans of architectural design.Oriented to bidding design requirements,this study integrates the intelligent design approach of building structure schemes and automates the entire design process,including structural design drawings,structural analysis models,and material consumption data.Subsequently,it was implemented in an actual bidding project.The results show that the efficiency of generative intelligent structural design for a single building is around 10 to 15 times greater than that of human design,and multiple project designs can be undertaken simultaneously.The structural mechanical qualities of intelligent design fulfill the criteria of the specification,and the material consumption is consistent with the engineer’s design.
