The research group coordinated by Dr. Joaquim Barros has launched a webtool, designated DABASUM (dabasum.civil.uminho.pt), a data base for FRP-based shear strengthening of reinforced concrete beams. In the present version – containing 442 examples of externally bonded and 69 examples of NSM repair – the collected information is used to assess the predictive performance of the fib, ACI, CIDAR and CNR design guidelines for the prediction of the contribution of FRP shear strengthening systems. DABASUM is also a forum where scientists and engineers doing research in this area can share and discuss ideas.
