It is seriously recognized in concrete engineering that concrete structures are no longer maintenance-free, and a number of the structures are going to reach their service-life limit.
According to the standard specification for concrete structures on maintenance by the Japan Society for Civil Engineers (JSCE, 2001), six deterioration mechanisms to be identified are specified for the maintenance.

Moment capacity of FRP reinforced concrete beam assessment based on centerline geometry Zatloukal Jan1,a, Konvalinka Petr1,b 1Experimental Centre, Faculty of Civil Engineering, Czech Technical University in Prague, Thákurova 7, Prague 6, CZ-166 29, Czech Republic ajan.zatloukal@fsv.cvut.cz, bpetr.konvalinka@fsv.cvut.cz Keywords: FRP, composite reinforcement, flexural behavior, moment capacity reduction based on member curvature.
(2) In engineering applications, where we assume the slope of the centerline to be small, we can approximate w’ ≈ 0 and as result the curvature from the previous equation will be equal to the second derivative alone, i.e. κ = w”.
Such high reduction is caused by very high curvatures the FRP reinforced members display at failure point, as the Young’s modulus of FRP reinforcement is by order of magnitude lower than the one of steel, resulting in much lower stiffness of the structural member (the fact which in engineering practice leads to Serviceability Limit State based design of FRP reinforced members).
The experimental program was conducted in the laboratories of the Experimental Centre of the Faculty of Civil Engineering of the Czech Technical University in Prague during the spring of 2011, as part of bachelor thesis of Filip Vogel [5,6].
