0引言 3月31日，国家标准《住宅项目规范》正式明确新建住宅层高不应低于3米。为应对这一行业规范的重要更新，我们迅速响应并对AIstructure-Copilot进行了针对性升级。新发布的V0.3.5版本，通过重新训练AI模型，显著提升了在3米层高条件下结构智能设计的力学性能合规率，旨在助力广大结构工程师高效满足新国标要求。诚邀各位试用并提出宝贵意见。1智能的关键在于具备学习的能力我们认同牛津词典对“智能 (Intelligence)”的定义，其核心在于具备“学习”的能力。在快速发展的当今世界，唯有持续学习与迭代，方能适应日新月异的技术标准与工程需求。AIstructure-Copilot采用生成式AI算法，通过对工程案例的不断学习，从而掌握新的技能，为该技术的未来发展提供了重要的潜能。这也是我们对智能设计这一技术的未来寄予厚望的重要原因。2适配3米层高建筑设计《住宅项目规范》对新建住宅的层高规定了新标准，并于今年5月1日起实施。新建住宅层高提升到不低于3米，在改善空间高度、提升室内天然采光、为住户提供更好的居住感受的同时，也对建筑抗侧刚度、层间位移角控制等有着直接的影响。AIstructure-Copilot此前的训练数据集很多基于2.8米层高的工程案例。当层高提升至3米后，原有模型生成的剪力墙布局、楼面梁配置等方案，在满足新规范的力学性能方面可能面临挑战。为解决此问题，我们首先依据新国标要求，对AI训练数据库进行了系统性的更新与扩充，确保纳入训练的工程案例均能在3米层高条件下满足各项力学性能规定。随后，我们采用更新后的高质量数据库对AI模型进行了重新训练，从而显著提升了AIstructure-Copilot在新规范下的设计质量与合规性。3提升合规性为检验AIstructure-Copilot-V0.3.5版本对3米层高建筑结构智能设计的可靠性，我们对单标准层建筑案例和多标准层建筑案例都进行了测试。结果表明，当层高提升到3米后，新版本设计的建筑结构力学合规率较此前版本提升了15%，使结构设计更加合理。典型案例如下：案例A： 如图1所示，某实际工程案例的标准层设计。在层高由2.8米调整为3米后，V0.3.4版本（图1a）的设计结果显示结构周期比为0.91，超出了规范限值要求。而0.3.5版本的设计结果如图1（b）所示，新版本的AI对部分剪力墙进行了延长，周期比为0.82，符合设计规范要求。 （a）0.3.4版本设计结果 （b）0.3.5版本设计结果图1 实际工程案例A的设计结果案例B：如图2所示，0.3.4版本的设计结果如图2（a）所示，由于层高从2.8米调整为3米，同样使得周期比超限了，0.3.5版本的设计结果如图2（b）所示，AI对部分剪力墙布置进行了调整，周期比为0.87，符合设计规范要求。 （a）0.3.4版本设计结果 （b）0.3.5版本设计结果图2 实际工程案例B的设计结果上述案例清晰表明，AIstructure-Copilot V0.3.5版本针对3米层高住宅的结构设计能力得到了显著增强。4结语通过对AI模型重新训练，AIstructure-Copilot-V0.3.5可高效适配新国标提升至3米层高后的结构设计，设计效果更好，力学合规率更高，带给用户更好的使用体验，可以更好的辅助工程师开展工作，欢迎大家试用。后续，我们还将不断完善相关产品功能。欢迎大家持续关注我们的工作，多多支持！ 温馨提示：为更好使用AI设计工具，请仔细阅读使用说明书(https://ai-structure.com)。--End--相关论文Liao WJ, Lu XZ, Huang YL, Zheng Z, Lin YQ, Automated structural design of shear wall residential buildings using generative adversarial networks, Automation in Construction, 2021, 132: 103931.
