Study on Bearing Capacity of Reinforced Concrete Column with Z-Shaped Cross-Section under Biaxial Eccentric Compression
Making use of the numerical analysis method, the bearing capacity of reinforced concrete column with Z-shaped cross-section subjected to biaxial eccentric compression was analyzed in this paper. Some factors affecting the ultimate bearing capacity of Z-shaped reinforced concrete column were studied, such as loading angle, ratio of axial compression, reinforced ratio, concrete strength and reinforcement arrangement in the limb. It is shown that the worst loading angle was near the second center bisector, the bearing capacity can be improved by enhance reinforced ratio, rebar strength or concrete strength, and the reinforcement arrangement in the limb had little effect on the bearing capacity.
