Abstract
A concrete tension member strengthened
2 with fiber reinforced polymer plates on two sides
3 is analyzed with non-linear fracture mechanics. The
4 analysis of the strengthened tension member incorpo5
rates cohesive properties for both concrete and inter6
face between concrete and strengthening medium, and
7 results in closed formsolutions for the load-crack open8
ing relationship. To distinguish between single and
9 multiple cracking in a design process, structural clas10
sification parameters are derived. The minimum rein11
forcement ratio for obtainingmultiple cracking derived
12 from the structural classification parameters, is inves13
tigated in a non-dimensional analysis, and found to
14 depend strongly on the ratio between interfacial and
15 concrete fracture energies.
