摘要

This paper reported the very earliest experimental and analytical studies on the bonded Prestressed CFRP tendon enhanced Steel Reinforced Concrete (PSRC) members under eccentric tensile loads. Eight PSRC members were tested under monotonic eccentric tensile loading, and three Steel Reinforced Concrete (SRC) members were simultaneously tested for comparison. The load–deflection relationship, the strain distributions as well as the crack propagation and fracture of concrete were investigated experimentally and analytically. The results demonstrated an improvement in the eccentric tensile capacity of PSRC members upon increasing both the steel and reinforcement ratios, or by reducing the prestress eccentricity. The results also suggested that an enhancement in the level of prestressing increased can decrease the crack propagation and lateral deflection. Moreover, the validity of the plane-section assumption was confirmed. An analytical model was proposed for predicting the elastic bending capacity of the PSRC members based on the experimental results. The study provided an in-depth understanding of the structural behaviour of PSRC members with bonded prestressed CFRP tendon under the eccentric tension underpinned by the elaborate experimental design and practical analytical model.
