Several ultimate load theories or "limit design theories" appropriate to reinforced concrete beams and frames recognize the ductility offered by suitably reinforced structural concrete. These theories assume that in properly designed statically indeterminate concrete structures, a full redistribution of moments takes place before failure due to the formation of plastic hinges. This 1961 experimental investigation had the primary objective of determining if it would be possible to disregard the problem of alternating plasticity (and incremental collapse) for reinforced concrete frames. Five frames were tested under both cyclic and proprtional loading.
