콘크리트 구조물의 중성화 및 LCC예측을 통한 최적 보수공법 선정

Abstract

콘크리트 구조물의 중성화 및 LCC예측을 통한 최적 보수공법 선정을 위하여 기존 데이터와 이를 종합 분석하여 유한요소법에 의하여 목표내용년수동안의 보수회수산정을 통한 LCC예측 기법을 제안함.;In this study, LCC(Life Cycle Cost) evaluation technique is used for the purpose of accumulation of basic data required for such integrative system construction. We predicted the degradation time of concrete and repair material by neutralization through FEM analysis, and utilized the result for LCC evaluation It turned out that the repair method of construction in the most economical initial measure against degradation and a durable period can be chosen through the LCC evaluation in consideration of the degradation prediction using FEM analysis and the initial construction expense in a durable period and repair expense, and the number of repair times.
