Topic: Defining interface bond.model
I’m using frp as external reinforcement for RC beam. According thé troubleshoot, I defined fibers as a discrete bars, but my first question:
1- The part of diameter bar: I can’t define cause the section of fiber not circle (about 5 mm width and 0.13 mm thick), so what the value in that case???
2- i already did the bond law slip that suits the frp materials and when I defined the cfrp discrete bars I changed the bond from perfect connection to the bond model that I did. However, the step for defining 3D interface between epoxy and concrete, the value of tensile strength??? This for epoxy or concrete????? Also cohesion and friction , the value of these points, for which of them????
I’m looking forward u reply
