세장비에 따른 철근콘크리트 장주의 크리프 좌굴 = Creep Buckling of the Reinforced Concrete Long Column according to Slender Ratio

다국어 초록 (Multilingual Abstract)

The rational design of RC long column is possible to consider load-moment Interaction, geometric nonlinearity of Ρ-Δ effect, crack, effects of creep and shrinkage in concrete under sustained load. In a slender column under sustained eccentric compression, the deformations caused by creep and shrinkage can lead to an increase in the loads on the structure and a reduction in strength. This study presents a methodlogy and improved computer program for the estimating creep buckling of the long column in considering slender effects and nonlinear behaviors. In this result, when slenderness ratio is greater than 80, we can know that magnified moment methods may be not applied in long columns.
