Crack resistance of this type of structures has become a critical design 24 consideration but received insufficient research attention in the past. In this context, the 25 anti-cracking performance of prestressed SRC columns reinforced with CFRP tendons 26 under eccentric tensile loads is investigated experimentally and analytically with the 27 following first-hand experimental validations: 1) prestressed CFRP tendons can well 28 strengthen SRC columns under eccentric tensile load and restrain the crack propagation; 2) 29 an increase in the load eccentricity progressively weakened the influence of prestressing 30 tension level on the cracking load; 3) specimens with the higher prestressed tension level, 31 larger longitudinal reinforcement diameter, and flange thickness exhibited greater crack 32 * Correspondent author: [email protected] (Hexin Zhang)
