BIM 기반 통합 RC 구조 철근모델링 자동화 방안

Abstract

구조공학분야의 BIM의 도입은 타 응용분야에 비하여 제일 먼저 정착되어 소개되기 시작한 분야로서, 국내에서도 상당한 관심을 가지고 설계사무소, 엔지니어링사, 건설회사 등에 소개되고 있다. 하지만 이러한 노력에도 불구하고 BIM Tool의 기능적 한계, 낮은 생산성 등 다양한 이유로 인해 적용 대상이 골조 모델에만 국한되어 있고, 철근콘크리트구조 특히, 철근 상세모델링 분야에서는 BIM의 활용은 제한된 범위 내에서만 이루어지고 있는 실정이다. 이에 본 연구에서는 BIM모델 활용 및 S/W의 한계로 인해 단순반복적인 수작업에 의존하는 철근 모델링 업무의 생산성을 제고하기 위한 목적으로 BIM소프트웨어에서 제공되는 기능을 활용한 철근 모델링 및 배근도 자동화 시스템을 개발하였다. 개발 시스템은 RC 연속보를 대상으로 하며, 구조해석 및 설계 결과로부터 구축된 부재 속성정보 DB와 배근일람표 DB를 기반으로 부재형상 및 속성정보와 배근설계값이 그대로 적용된 모델을 자동으로 생성하는 기능과 연속보 특성에 맞는 이음/정착을 자동으로 수행하는 기능을 갖는다. 이를 통해 건축구조분야 BIM Tool의 기능 및 생산성을 향상시키고 나아가 구조분야의 BIM도입 및 활용범위를 확대고자 하였다.|As BIM (Building Information Modeling) was introduced and settled in the field of structural engineering earlier than any other application field, it still attracts lots of interest and is also introduced to design offices, engineering companies and construction companies in Korea. Despite such endeavors and interest, however, its application targets are limited to frame models for such reason as functional limits and low productivity of BIM tools, and BIM is actually applied to a limited range in the field of rebar modeling, especially for RC (reinforcement concrete) structures. Thus, this study investigated plans to automatize rebar modeling and rebar shop drawing in order to improve the productivity of rebar modeling attributed to repetitive handwork due to the limitations of BIM model application and S/W. Particularly, this newly-developed system aims at RC continuous beams and is based on member parameter DB and RC design DB. Through the DB established, this system creates a model with member property, parameters and RC design values automatically applied as they are, carries out splices and anchorages fit for the characteristics of continuous beams and finally extracts rebar shop drawing. The purpose of this study improves the functions and productivity of BIM tools in the field of building construction and expands the range of BIM introduction and application in the field of structural engineering.; As BIM (Building Information Modeling) was introduced and settled in the field of structural engineering earlier than any other application field, it still attracts lots of interest and is also introduced to design offices, engineering companies and construction companies in Korea.
