Construction of RC frame requires a considerable amount of reinforcement steel bars. Shaping market length rebars to get design lengths leads to the production of waste. The purpose of this research is to optimize the use of available market length rebars in such a way that will generate the least possible waste. Accordingly, Building Information Modeling (BIM) based automated framework integrated with Mixed-Integer Linear Programming (MILP) has been presented in this article. This methodology involves extracting reinforcement detailing data automatically during the design phase using BIM. Then, implementing the column generation algorithm to generate only necessary cutting patterns. Then, optimizing the use of market length rebars by applying the MILP approach. An RC frame of a three-storied building has been analyzed to evaluate the efficiency of the proposed framework. The results show that a substantial amount of trim waste reduction can be achieved quickly and efficiently by the suggested method.

使用建筑信息模型和混合整数线性规划的钢筋混凝土框架结构中的钢筋补强废物自动优化

RC框架的构造需要大量的钢筋。调整市场长度的钢筋以获得设计长度会导致浪费。这项研究的目的是以可产生最少浪费的方式优化可利用的市场长度钢筋的使用。因此,本文介绍了基于建筑物信息建模(BIM)的自动框架,该框架集成了混合整数线性规划(MILP)。这种方法涉及在设计阶段使用BIM自动提取钢筋细部数据。然后,实施列生成算法以仅生成必要的切割模式。然后,通过采用MILP方法来优化市场长度钢筋的使用。分析了三层建筑的钢筋混凝土框架,以评估所提出框架的效率。结果表明,通过所建议的方法可以快速有效地实现大量的装饰垃圾减少。
