摘　　要：当前国内装配式建筑的装配率都是在设计阶段根据施工图纸按照相关规范进行人工计算,这种计算方式产生了大量的时间和人力的成本,且同一种计算思路,所得结果也不尽相同,正确率难以得到保证。鉴于此,本文提出了一种基于BIM的计算方法,以.Net Formwork4.7为框架采用C#语言,对BIM核心软件Revit进行二次开发,将《装配式建筑评价标准》以及规定的装配率计算方法编入插件中,通过建立构件自定义编码体系,识别并获取构件数据信息,来计算装配式预制混凝土(Precast Concrete,简称PC)的主体结构装配率。最后以实际工程项目为例,验证本方法的可行性。研究表明,通过这种方式大大减少计算时间与人力成本,并提高了精度。At present,the assembly rate of prefabricated buildings in China is calculated manually under relevant specifications according to construction drawings at the design stage.This kind of calculation generates a lot of time and labor costs.Moreover,the same calculation method has different results,and the accuracy is difficult to be guaranteed.In view of this,this paper proposes a calculation method based on BIM.With.Net Formwork4.7 as the framework,C#language was used to carry out secondary development of BIM core software Revit.And the assembly rate calculation method stipulated in the Prefabricated Building Evaluation Standard is incorporated into the plug-in,and the assembly rate calculation of the main structure is realized by establishing the component custom coding system,identifying and obtaining the component data information to calculate the assembly rate of main structure of Precast Concrete(PC).Finally,this paper uses a practical engineering project as an example to validate the feasibility of this method.The research shows that the calculation time and labor cost are greatly reduced and the precision is improved.
