Revit 기반 구조 모델링의 철근 배근을 위한 Dynamo 활용 방안 연구

초록

Efforts to improve construction productivity by adapting advanced technologies have been made continuously throughout the construction industry. Building information modeling (BIM) is being applied in various construction fields. However, BIM application is limited mostly to structural frame modeling. In addition, the BIM tool has not been widely used in practice owing to its time-consuming and repetitive work and its limited rebar modeling functions. Therefore, this study proposes a method to increase engineers' accessibility and work efficiency in utilizing BIM by automating the rebar placement tasks via parametric modeling and visual programming (Dynamo). An L-shaped retaining wall, which has a relatively complex shape among the civil reinforced structures, was selected as the target of algorithm development and conducted the parametric modeling after selecting various parameters. In addition, an algorithm for the rebar arrangement automation on the BIM object was constructed using Dynamo and Excel. The results showed that working hours were lower than those taken using the rebar modeling function of the existing commercial BIM tools. Moreover, after modifying only a part of the algorithm, reusing these algorithms in various components or similar projects can contribute to the productivity of BIM-based rebar arrangement modeling tasks.
