rupture strain of FRP

Hi everyone. I have to use FRP to retrofit the piers of the bridge. We need to calculate tensile strain in the FRP at hoop rupture to model the FRP in the Opensees. I have read in the papers that we have to calculate the rupture strain of FRP by doing a coupon test. I'm not able to do this test by m...

FRP Material

Hi everyone I have to create a FEM model of an RC bridge pier retrofitted with FRP. I used Concrete07 for all bridge piers and developed fragility curves of the not retrofitted bridge. Now, I want to retrofit bridge piers with FRP and develop fragility curves for the retrofitted system. Which materi...

FRPConfinedConcrete Units

Hi everyone. I have to create a FEM model of an RC bridge pier retrofitted with FRP. If I wanted to use from FRPConfinedConcrete or ConfinedConcrete01, I would have to enter inputs in MPa and mm units, while all the inputs were entered in Pa and m units. What should I do to solve this problem? If th...
