WebA uniaxial cyclic model for confined and unconfined concrete is developed. Starting from an existing model, the cyclic rules to define inelastic strain and degradation of strength and stiffness are first reviewed and then modified to produce a new concrete model with enhanced performance. Comparisons at the stress-strain level between the new and … WebA stress-strain relationship to represent the overall behavior of reinforced concrete in tension, which includes the combined effects of cracking and slippage at cracks along the reinforcement, is proposed.
WebIf this strain is prevented, it produces tensile stress in the concrete and hence concrete develops cracks. 7. Modular ratio ...
