$P-{\Delta}$ 영향을 화해를 입은 기둥의 거동
Structural Behavior of Fire-Damaged Reinforced Columns with $P-\Delta$ Effect
초록
The paper discusses the general behavior of fire-damaged slender reinforced concrete columns on the basis of results obtained from parametric studies. Effects of slenderness ratio, concrete strength, cover thickness, reinforcement ratios, exposed time to fire, and eccentricity on the ultimate capacity of fire-damaged column are theoretically observed. With the increase of slenderness ratio, similar tendency of relative strength reduction was observed between fire-damaged columns and columns at room temperature.
