사용성 한계상태를 적용한 초고층 콘크리트 건물 기둥축소량의 구조신뢰성평가

Differential shortening effects in tall concrete buildings causing cracks of partitions, curtain walls and pipe lines are a significant serviceability component. The paper describes a method for the structural reliability assessment on serviceability limit state of the time-dependent column shortening. The method is based on the probability analysis using monte carlo simulation. Based on the reliability index and probability of failure, the column shortening of 41-story tall concrete building is evaluated quantitatively and the compensation values are proposed considering target reliability index on the serviceability limit state.
