Abstract

The objective of the study is to establish a BIM modeling of precast concrete(PC) shear wall with various wall-to-base connections. The family library of PC shear wall was established in BIM program using component function in a IFC(Industry foundation classes) file format and SketchUp program. From the BIM program, the amounts of concrete, reinforcing bars and steel materials as well as the interference of arranged reinforcing bars can be accurately evaluated in the PC shear walls with spliced sleeves, bolt, or welding plate connection methods. Although the additional metallic materials such as steel plates, bolts, and nuts were used in the PC shear walls with welding plate connection method, their amounts of materials, economic efficiency, and environmental impact were similar to those with spliced sleeve connection. Consequently, the bolt or welding connection is a highly applicable method as wall-to-base connection of PC shear walls, and it was a more useful method than spliced sleeve method, particularly considering the constructability.

이 연구의 목적은 다양한 접합상세를 갖는 프리캐스트 콘크리트(precast concrete, 이하 PC) 전단벽에 대한 BIM 모델링 절차를 정립하는 것이다. 그 결과 스케치업(SketchUp)의 프로그램과 컴포넌트 기능과 IFC(Industry foundation classes)파일 형식을 이용하여 BIM 프로그램에서 사용가능한 PC 전단벽 패밀리 라이브래리를 구축 할 수 있었다. 스플라이스 슬리브, 볼트 또는 용접접합공법을 이용한 PC 전단벽은 BIM 프로그램으로부터 배근된 철근들의 간섭여부와 콘크리트, 철근 및 철재 재료들의 물량을 정확히 평가할 수 있었다. 평가 결과 용접접합 공법을 이용한 PC 전단벽은 판재, 볼트 및 너트를 사용하였음에도 스플라이스 슬리브로 연결된 PC 전단벽에서 사용된 재료들의 전체물량, 경제성 및 환경영향성이 비슷한 수준에 있었다. 결과적으로 볼트 또는 용접접합 공법은 PC 전단벽에서 적용가능성이 높은 공법이며, 특히 시공성까지 고려한다면 스플라이스 슬리브 공법보다도 더 유용한 연결공법이 될 것으로 판단된다.
