Deflection prediction of reinforced concrete beams by ...

01/11/2013  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. The behaviour can be highly non-linear and challenging for calculation of deflections.

CE 433, Fall 2006 Deflection of a Reinforced Concrete Beam

The deflection of reinforced concrete beams is complicated by several factors. 1) The connections of a cast-in-place reinforced concrete frame usually transfer moment. The mid-span deflection of a beam in such a frame is affected by the stiffness of the members framing into the beam ends. The mid-span deflection can be calculated by solving two simultaneous equations for the rotations at each ...
