Correspondence on The Effect of External Plate Reinforcement on the Strength of Structurally Damaged RC Beams by Dr. R.N. Swamy, Mr. R. Jones and Dr. A. Charif

Mr A. C. G. Hayward (F) (Cass Hayward & Partners): The paper broadly demonstrates that external plate reinforcement glued to a loaded structure is as effective as if it had been firstly relieved of load. This is reassuring to engineers seeking economic strengthening measures. Relieving a structure of load (or stress) before strengthening can be prohibitively expensive. The economy and feasiility of glued plates could be further enhanced if traffic was allowed to use the structure while the glueing and curing process was actually taking place. Could the authors comment on this possibility and whether research is warranted or possible.
