Design of Shear Strengthening

The value of the design strength of shear strengthened members can be computed 

For U-wrap or total-wrap configurations on a rectangular cross-section, the contribution of the FRP strengthening, VRd,f, can be evaluated according to the Moersch truss mechanism and is equal to  

For effective design strength control in the case of U-wrap, the following relation can be applied
