shell99

hi everyone,           i attached FRP strip and u-wraps to the concrete beam. i simulate it in ansys using shell 99 for FRP strip and uwraps. but i have a problem that the beam behaves as if the FRP does not work, and the failure load is as the same for the beam without FRP. however i merged the joints between FRP strip and uwraps and the concrete joints. i hope if somenone knows the reply, i need this reply very soon.  thank you so much for cooperation.
