The Optimum Design of Reinforced Concrete Structures Based on the LRFD
하중일- 저항계수 설계법에 의한 철근콘크리트 구조물 최적설계
Abstract
In this study, an optimization design of reinforced concrete structures is performed by using the structural optimization techniques based on the LRFD criteria. The target reliability index is estimated by the optimal reliability index considering the expected cost which is taken as a sum of the structural cost and the expected costs due to failure of the structure. The load and resistance factors calculated by using level I reliability theory with the target reliability index are compared for each load combination (D+L, D+L+w). The results of this study show that the resistance factors are
