| 摘要： | An experimental investigation was conducted to study the influence of deformability behavior in carbon-fi-ber-reinforced polymer (CFRP) prestressed concrete beams. The moment curvature of CFRP prestressed beams does not follow the linear stress-strain curve,showing that there is some amount of energy absorbed, which influences the serviceability behavior of members. Four beam specimens were cast, stressed at deformability index values varying from 1.35 to 2.88, and tested. Numerical analysis was conducted using the experimental results. It was concluded that the deform-ability of beam influences the serviceability behavior of the beam and proposed new deflection model. The proposed model is an efficient method for calculating deflection compared with the ACI 440.4R-04 method. A design chart is suggested for calculating effective moment of inertia and effective neutral axis distance. The influence of the deformability index in crack width, crack spacing, number of crack pattern, and crack stabilization load are also described. |
