Fracture mechanical analysis of strengthened concrete tension members with one crack
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.
