Study on reinforce prestressed hollow slab by CFRP

This paper focus on the material property and cross-section bearing capacity under a reinforcement of CFRP, and it compares with the previous state without being reinforced. The author conducts the nonlinear analyze upon the model and the results, in the case of a same load and different steel ratio, or in the case of a same load ratio and a different quantity of CFRP, in order to find out the ultimate capacity, the ultimate displacement and other date, and to compare the effect of CFRP reinforcement in different steel ratio and also the theoretical value.
