Correspondence on Structural Behaviour of Externally Bonded, Steel Plated RC Beams After Long-Term Exposure by Professor R.N. Swamy, Professor B. Hobbs and Mr M. Roberts

Dr D. J. Oehlers (University of Adelaide, Australia) I would like to congratulate the authors on an interesting paper and particularly Professor Swamy whose research in this area has provided the foundation for the application of this technique. I note that all the specimens had very thin plates of 1.5mm. Is this size plate used in practice, and would the authors suggest that thicker plates could be used? My own experience has shown that roughening the surfaces of very thin plates by sandblasting prior to gluing is very difficult as it leaves excessive deformations in the plate.
