Abstract

To study the behavior of coral aggregate concrete (CAC) column under axial and eccentric compression, the compression behavior of CAC column with different types of steel and initial eccentricity (e_i) were tested, and the deformation behavior and ultimate bearing capacity (N_u) were studied. The results showed that as the e_i increases, the N_u of CAC column decreases nonlinearly. Besides, the steel corrosion in CAC column is severe, which reduces the steel section and steel strength, and decreases the N_u of CAC column. The durability of CAC structures can be improved by using new organic coated steel. Considering the influence of steel corrosion and interfacial bond deterioration, the calculation models of N_u under axial and eccentric compression were presented.
