摘　　要：钢筋作为建筑施工三大主材之首,是施工项目成本与质量控制的重点。但是国内现有的钢筋下料工作基本都由手工翻样完成,并且极度依赖施工现场的技术经验。本文按照钢筋下料的工作流程作为主线,以“结构安全、施工方便、经济节约”作为评分原则,结合钢筋图集规范与施工习惯,借助图形几何算法,在Revit软件上做二次开发,对柱墙梁板等构件进行钢筋下料的计算,用预设的程序进行多种方式的钢筋排布预演,并根据钢筋排布方式产生得结果打分择优,以此找到钢筋下料最优解,并将相关的计算数据通过外部数据库文件的方式储存。本程序以南京公安大楼作为案例,实践并测试算法的稳定性,结果表明,对比传统钢筋下料手段,能够实现节约材料,低碳施工的目标。As the most significant element of the three main materials of building construction,reinforcement is the main concern of cost and quality control in construction project.However,the existing reinforcement blanking work is basically completed by manual lofting in China,and it is extremely dependent on the technical experience of the construction site.Taking the work flow of steel bar blanking as the main line,this paper upholds the three scoring principles:structural safety,convenient construction and economic saving.What’s more,combining with the specification of steel bar atlas and construction habits,this paper makes secondary development on Revit software with the help of graphic geometry algorithm,calculates the steel bar blanking of columns,walls,beams and slabs,etc.,and further carries out various ways of steel bar layout rehearsal with preset programs.Moreover,the best is scored according to the results of reinforcement arrangement so as to find the optimal solution of reinforcement blanking,and the relevant calculation data are stored in the form of external database files.This paper takes Nanjing public security building as a case to practice and test the stability of the algorithm.And its results show that it can succeed in saving materials and low-carbon construction compared with the traditional reinforcement blanking methods.
