Abstract

LCC 분석은 건축물의 설계단계 뿐만 아니라 유지관리 단계에서의 보수 보강 또는 교체에 대한 최적 의사결정의 도구로서 이론적으로나 실무적으로 각광을 받고 있는 분석 방법이다. 이는 초기 투자비용의 효율성을 극대화 하고 유지관리를 통한 구조물 사용성의 효율적 증대를 극대화하는 노력의 일환으로 최근 건축물의 설계 및 유지관리 시 LCC 분석효과의 실질적인 적용이 요구되어 지고 있다. 따라서 본 논문은 일반적인 분석기법에 그치고 있는 기존 LCC 연구를 생애위험도를 고려한 LCC분석을 통해 설계단계 최적 의사결정을 위한 새로운 분석 방법론을 도출하였다. Recently, the demand on the practical application of life-cycle cost effectiveness for design and rehabilitation of structure is rapidly growing unprecedently in engineering practice. Accordingly, in the 21st century, it is almost obvious that life-cycle cost together with value engineering will become a new paradigm for all engineering decision problems in practice. However, in spite of impressive progress in the researches on the LCC, the most researches have only focused on the Deterministic or Probabilistic LCC analysis approach (Level-1 LCC Model) at design stage. Thus, the goal of this study is to develop a practical and realistic methodology for the Lifetime risk based Life-Cycle Cost (LCC)-effective optimum decision-making at design stage.
