装配式结构的建筑信息技术正向设计

Forward Design of Building Information Technology for Prefabricated Structure

通过比较分析建筑信息技术在建筑工程项目设计中普遍使用的逆向设计方法,提出结构设计阶段运用正向设计的思路.并根据建筑信息技术为建筑工业化和数字化服务的特性,以建筑信息模型为依托,阐述了在建筑工程结构设计阶段使用正向设计方法的优势;分析在建筑信息技术支撑下进行结构正向设计的方法,以解决结构信息模型在力学计算、施工图绘制等方面的协同设计作业;以装配式结构为例,用建筑信息技术正向设计的方法,实现三维模型、模型结构计算分析、施工图绘制和配式构件深化的设计.

Through the comparative analysis of the reverse design methods commonly used in the construction project design of building information technology,this paper puts forward the idea of using forward design in the structural design stage.According to the characteristics of building information technology serving for building industrialization and digitalization,based on building information model,this paper expounds the advantages of using positive design method in the structural design stage of building engineering;analyzes the method of carrying out structural positive design under the support of building information technology,so as to solve the collaborative design work of structural information model in mechanical calculation,construction drawing,etc Taking the prefabricated structure as an example,the forward design method of building information technology is used to realize the three-dimensional model,the calculation and analysis of model structure,the drawing of construction drawings and the deepening design of matched components.
