Evaluation of time-dependent strain loss in CFRP eccentrically reinforced Shrinkage Compensating Concrete (SHCC) flexural members
Abstract Eccentrically CFRP enclosed Shrinkage Compensating Concrete (SHCC) flexural members show benefits of easy prestressing, better durability and self-made camber compared with traditional prestressed concrete. This paper presents the experimental and analytical work to evaluate the expansion strain losses in the proposed flexural members. A proposed analytical model to calculate the time-dependent strain losses is established including variables of shrinkage and creep of SHCC concrete based on GL2000 model. The relationship between maximum expansion strain and axial stiffness of FRP (EA) is also constructed. The same procedure was also conducted for Portland Cement Concrete (PCC) for the CFRP-PCC beam specimens. It is indicated that the proposed analytical model produces an accurate prediction in strain losses over time.
