An Innovative Approach to Strengthening Steel and Concrete Structures

As they age, steel and concrete structures often need to be retrofitted. One such way of strengthening is with Carbon Fibre Reinforced Polymer – or ‘CFRP’ – laminates. For certain applications, however, this can be a difficult and time-consuming process, and the resulting laminates are prone to debonding. In his research, Dr Abheetha Peiris at the University of Kentucky developed a new type of strengthening in the form of CFRP strip and rod panels. The panels can slot together seamlessly – making them less prone to failure, and far easier to assemble. Through a series of experiments and field applications, he revealed how the new method can be applied for retrofitting both steel and concrete structures.
