Procedures for Long Term Testing of Reinforced Concrete Tension Specimens

Abstract:

Long term tension stiffening effects in beams and slabs were investigated by a comprehensive series of laboratory tests on tension specimens together with a small number of slabs. Some tension specimens contained strain gauged rebars to obtain very detailed data concerning reinforcement strain distributions. The results indicated that tension stiffening decayed much more rapidly than was previously thought and the important implications of this finding on the current design rules for deflection control are indicated.
