Study on crack width and crack resistance of eccentrically tensioned steel-reinforced concrete members prestressed by CFRP tendons

In recent decades, steel-reinforced concrete (SRC) members under eccentrical tension have been adopted more frequently in modern buildings due to the constraints of complex structural design/detailing that accompanying contemporary architectural creations. Crack resistance this type structures has become a critical design consideration but received insufficient research attention past. context, anti-cracking performance prestressed SRC columns reinforced with CFRP tendons eccentric tensile loads is investigated experimentally and analytically following first-hand experimental validations: 1) can well strengthen load restrain crack propagation; 2) an increase eccentricity progressively weakened influence prestressing level on cracking load; 3) specimens higher level, larger longitudinal reinforcement diameter, flange thickness exhibited greater capacity. Furthermore, plane-section assumption was also validated study. A test data-enhanced analytical method proposed for determining PSRC columns.
