An Experimental Study On the Inelastic Behavior of the High Strength Reinforced Concrete Column subject to Monotonic Loads

단조 하중을 받는 고강도 철근 콘크리트 기둥의 비탄성 거동에 관한 시험적 연구

This research is related to the experimental investigation of the inelastic behavior of R/C columns with high strength concrete. A total of eight specimens have been tested with different span ratios, steel reinforcements and load applications. Through tests bending moments were applied incrementally while axial forces being kept constantly at 80 tons. Careful observation were given to initial crack formation, crack patterns and propagation paths. Comparative studies have been made on the load carrying capacity for R/C columns with high strength concrete versus normal strength concrete.
