Abstract

Since the structure systems of construction projects have been forced to be large, high-rised, and complex, many researchers have been put their efforts to develop high strength concrete incorporating diverse advanced materials. In order to improve the performance of the concrete, the fibers leading high ductility to concrete have been used, consequently concrete columns adopting High-Performance Fiber Cement(HPFC) have been developed. This paper analyzed not only the construction work process of HPFC column installed to the real construction project, but also construction productivity of the columns by using discrete event simulation technique. As a result, several considerations on installing such a column have identified, compared with the works for typical concrete columns. In particular, there was specific characteristic to install the columns in terms of labor resource productivity, which is not shown with the work for the typical concrete columns.

최근 건설 구조물의 다양화, 대형화, 고층화 및 장지간화 되면서 콘크리트 구조재료에 관한 고성능화가 요구되고 있으며, 특히 콘크리트의 고강도 및 고성능화가 대두되고 있다. 콘크리트의 고성능화 및 재료 특성을 개선하는 방법으로 주로 첨단소재 기술에 의해 개발된 첨단 섬유를 적용하는 방법이 사용되어 왔으며, 고성능 섬유시멘트 복합체(이하 HPFC)를 적용한 콘크리트 기둥 공법이 그 중 하나이다. 본 연구는 시뮬레이션 기법을 활용해, 일반 RC 기둥 대비 프리캐스트 기법이 적용된 HPFC 기둥 공법 공정에 대한 작업프로세스를 분석함과 동시에, 수집한 작업데이터를 통해 HPFC 기둥 공법의 공정계획상 이슈를 도출하였다. 그 결과 생산성에 가장 영향이 큰 작업(노드)로 '콘크리트 작업조', '형틀 작업조'로 도출되었으며, 특히 '콘크리트 작업조'가 공정계획상 가장 중요한 요소로 작용함을 확인할 수 있었다. 해당 작업(노드)에 투입되는 작업조 수 변화를 통한 생산성 향상을 확인하였으며 본 연구를 바탕으로 HPFC 기둥 공법의 실용화 단계에 도움이 될 것으로 예상된다.
