This paper reviews investigations into a novel composite of concrete and steel, particularly as relating to seismic resistant structures. The primary novelty is that all the steel reinforcement, whether required for tensile or shear resistance, is provided as sheet rather than bar. This sheet steel is fabricated into closed box sections insi de which the concrete is cast insitu and hence fully contained. The sheet is not profil ed or specially prepared. The composi material made in this manner has been termed 1s t e Externally Reinforced Concrete, and abbreviated to ERC. The material is very strong and ductile and offers scope for simplification and cost savings in construction.
