In this paper, the strengthening of two-way slabs using CFRP is evaluated experimentally and analytically. The reinforcement ratio equal to 1.4% was chosen to serve the purpose of demarcating the punching shear failure mode. Results show that the punching capacity of two-way slabs can increase to 40% over that of the reference specimen. Moreover, a 3D FEM program named “3D CAMUI”, which was developed at Hokkaido University, was used to simulate the experimented slabs. Very good agreement is obtained in terms of load carrying capacity and modes of failure. |
