Example 2: Strengthening a beam with near‐surface‐mounted CFRP strips
The downstand beam, which was designed as a simply supported member, is to be strengthened with near‐surface‐mounted CFRP strips. The load combination for the ultimate limit state and the load combination for the serviceability limit state under a rare load combination are required for the analyses. The prestrain at the level of the near‐surface‐mounted CFRP strips is calculated using the prestrain in the reinforcement steel. This chapter determines the point on the unstrengthened member at which the existing reinforcing steel reaches its yield point under the loads in the strengthened condition. The design value of the bond strength of all externally bonded reinforcement is obtained by multiplying the tensile force that can be anchored per strip by the number of strips. The chapter analyses the shear capacity of the downstand beam according to DIN EN 1992‐1‐1 and its associated National Annex.
