Prestressed concrete sleeper design: Loading tests on model beams to investigate the actual eccentricity of prestress and compare it with the theoretical (TM-TS-10)

Reference has been made in two reports concerning concrete sleepers, that the actual eccentricity of prestress might be different from the theoretical, and this memo describes an investigation into this feature by using model beams. The investigation revealed that the actual eccentricity of prestress was always less than the...
