Deflection prediction of reinforced concrete beams by ...

Nov 01, 2013  1. Introduction. Deflection response of cracked reinforced concrete (RC) elements is a complex process including a wide range of effects, such as, different strength and deformation properties of steel and concrete, cracking, tension–softening and tension–stiffening, and bond slip between reinforcement and concrete.

Deflection predictions varied significantly (in a statistical sense) with change in load intensity and reinforcement ratio and improved with increase of these parameters. Significantly larger prediction scatter was obtained for the members with small reinforcement ratio (p ⩽ 0.4%) and at early cracking stages. It was found that accuracy of ...
