Abstract: Because the behaviour of reinforced concrete is extremely complex, research over the past seventy years has concentrated on developing safe design rules for national standards for what might be referred to as standard members in standard environments: standard members being RC members with normal concrete and with ductile steel reinforcement that has a very good bond with the concrete; and standard environments being structures subjected to wind and gravity loads. Furthermore, to allow the rapid application of reinforced concrete, many of the design rules in national standards were derived by testing. An example is the concrete component of the shear capacity which is purely empirical yet absolutely essential in the design of RC members. Being empirical, these rules in national standards can only be used within the bounds of the testing regimes from which they were derived that is for standard members in standard environments. Over the last ten years, structural engineers have been faced with finding solutions to problems outside the scope of the standard environment such as the ability to resist seismic or blast loads, and to include new technologies which might help in the new environment such as: non-ductile steel reinforcement; brittle FRP reinforcement; very high strength concrete; steel and FRP confined concrete; and FRP polymer fibre concrete. Because these applications are not covered by the empirical design rules in national standards, the engineer has the choice of either repeating the enormous amount testing that has made standard members in standard environments safe which can be very expensive, or to use more advanced structural mechanics models to replace the empirical models in national standards which is the subject of this presentation. It will be shown that these new structural mechanics models can be made very simple and are much more versatile, which should allow non-standard structures such as the use of FRP reinforcement to be designed with confidence.
