ABSTRACT
Mr Ness: In the reinforced concrete beams shown under the test arrangement, there were rollers at each end, and the beam is larger at the ends. Do you think that the restraint at the ends due to the extra length rna cause results to deviate from the beam behaviour. Dr Jeyarupalingam: The small overhang is necessary for realising the support. Since this is a free cantilever, there should not be a significant influence, since the beam is effectively shielded beyond the support. A small degree of heat loss will occur, but then the end conditions are far from perfect anyway.
