基于Dynamo的民用建筑防火参数化设计方法--以疏散宽度设计为例

Research on parametric design method of civil building fire prevention based on Dynamo:a case study of evacuation width design

为了研究参数化防火设计方法和技术,从“分”与“合”的角度探讨了防火规范编制与实际设计流程的矛盾,确定了按照正向设计逻辑将离散的规范条文组织为完整、标准化的设计算法和设计工具的研究思路。对防火规范和其他专项建筑规范中相关条文和设计参数进行系统性梳理,将设计流程总结为建筑定性、疏散宽度计算和疏散宽度校核与设计3个部分,进而建立整体设计逻辑模型。基于计算性设计思维的技术和方法,总结了从设计规范的自然语言向算法的程序语言转化的一般方法,提出了符合实际设计流程和习惯的参数化设计算法,从理论和应用两个方面对参数化设计工具和方法在民用建筑防火设计中的应用进行了初步探索。

To explore parametric fire prevention design methods and technologies,the contradiction between the preparation of fire prevention code and the actual design process was discussed from the perspective of“separation”and“combination”,and the research idea was proposed of organizing discrete code provisions into a complete and standardized design algorithm and tool according to the forward design logic.The design process was summarized into three parts,i.e.,building characterization,evacuation width calculation and evacuation width verification and design,by systematically sorting out the relevant provisions and design parameters of fire prevention codes and other special architectural design codes,so as to establish the overall design logic model.Based on the techniques and method of computational design,the general method of transforming the natural language of design specification into the program language of algorithm was summarized,and the parametric design algorithm was put forward according to the actual design process and habits under the guidance of applicability and convenience.It makes a preliminary exploration from both theory and application into the application of parametric design tools and methods in civil building fire prevention design.
