摘要:冷弯薄壁型钢结构住宅因其自重轻，地震响应小，安装精度高，在有快速建造需求的低多层轻钢结构住宅中有比较广泛的应用。但是，由于行业内相关的结构建模和计算软件的限制，冷弯薄壁型钢结构的设计一直停留在二维设计层面。本文通过创新开发的Revit插件，实现了冷弯薄壁型钢结构的BIM正向设计，并集成搭载自动建模和结构计算的全专业协同设计平台。通过基于功能的模块化户型设计，组合形成多样化的户型平面；初步建立了适合冷弯薄壁型钢复合墙板房屋各功能空间的开放性模块化数据库，为建筑设计深化和墙板标准化拆分提供依据；融合BIM建筑智能化系统，实现快速龙骨生成与三维建模、生成计算书与设计图、深化详图与算量、对接生产制造设备和生产制造数据自动传输等功能，支持轻钢龙骨的智能化生产。

Abstract: The cold-formed thin-walled steel structure residence is widely used in low-rise light-steel structure residence with rapid construction demand because of its light weight, small seismic response and high installation accuracy. However, due to the limitations of the relevant structural modeling and calculation software in the industry, the design of cold-formed thin-walled steel structures has always remained at the two-dimensional design level. This paper has innovated the secondary development plug-in based on Revit2017, and realized the BIM positive design of cold-formed thin-walled steel structures for the first time in the industry, and integrated a full-professional collaborative design platform with automatic modeling and structural calculation. Through the function-based modular house design, the industrial product thinking is introduced in the design stage. Considering different living needs, the functional spaces e.g. bedroom, living room, kitchen and bathroom are designed into several standardized functional modules, which form a diversified flat through module combination. An open modular database suitable for each functional space of cold-formed thin-walled steel composite wallboard houses has been initially established, which provides a basis for deepening architectural design and standardization of wallboard splitting. Integrating the BIM intelligent building system and compiling the algorithm according to the specification requirements, the intelligent production of light steel keel has been realized in the design stage by realizing the functions include: rapid keel generation and 3D modeling, generation of calculation sheets and design drawings, deepening of details and calculation, docking of production and manufacturing equipment and automatic transmission of production and manufacturing data.
