Study of Stiffness Calculation Method on Reinforced Concrete Beam Strengthened with CFRP

Han, Xue / Liu, Zheng / Xu, Xin / Ge, Chao

The beam member should not only meet the requirement of carrying capacity but also has the ability to resist deformation. The calculation of beam deflection mainly boils down to the stiffness calculation in the existing calculation theory of deformation capacity. The flexural stiffness of concrete beams after strengthened with CFRP has been improved greatly. Direct reinforcement and sustained load reinforcement short-term stiffness calculation methods of CFRP reinforced concrete in normal service stage are derived in this article, which could be used for strengthening design.
