Abstract:
Current code provisions for deflection calculations in reinforced concrete beams and slabs are discussed. A comprehensive series of laboratory tests to investigate long term tension stiffening effects is summarised, results from which indicated that tension stiffening decays much more rapidly than was previously understood. Revised code provisions are proposed based on this finding.
