TENSION STIFFENING MODEL FOR REINFORCED CONCRETE MEMBERS

The principal difficulty in modelling the moment-curvature relationship for a reinforced concrete element is the influence of flexural cracking, the tensile strength of the concrete between the cracks, bond slip and the non-linear stress-strain relationship of the concrete especially as influenced by creep. A simple theory based on the deformation and equilibrium at a cracked cross-section may be easily derived if the influence of the tension stiffening of the concrete between cracks is taken into account by a hypothetical stress-strain curve for the reinforcement. Typical curves have been obtained from experimentally observed values of bending moment, curvature and compressive concrete strain using the calculus of variations. (Author/TRRL)
