基于BIM体系的钢筋优化下料初探

Preliminary Procedure Study on BIM-based Steel Bars Picking Optimization

钢筋工程是混凝土框架结构中的组成部分,在造价中占有很大的比例。传统钢筋下料面临算量偏差、裁切无章等问题,造成不必要钢筋成本增加。运用BIM虚拟仿真技术可指导实际工程,研究从(1)施工深化设计和(2)钢筋优化下料两方面展开,讨论将BIM技术和优化算法结合,建立基于Revit实体配筋技术导入钢筋下料优化方法初步程序。为后期开发下料插件提供思路,以达到优化钢筋的下料,减少资源的浪费。

Reinforced concrete（ RC） is a component of a concrete-based frame structure. It accounts for a large proportion of the cost. Traditional steel bars picking has such problems as deviation calculating the amount of material,picking no effective rules and so on,which lead to unnecessary increase of steel bars cost. Building information modeling（ BIM） virtual simulation technology can guide the actual engineering. This study focuses on two major aspects：（ 1） detail construction design and（ 2） steel bars picking to combine BIM technology and optimization algorithms to establish a preliminary procedure of BIM-based Revit reinforcement and steel bars picking methodology. This study provides ideas for later development of BIM-based steel bars picking plug-in software to achieve steel bars picking optimization and reduce waste of resources.
