Abstract

In this paper, effects of restraint degree and reinforcement on concrete restrained stress have been analyzed based on the age-adjusted effective modulus method (AAEMM). Based on principle of deformation compatibility and force equilibrium, formulations relating to the stress and strain of reinforcement and concrete have been derived; meanwhile, the calculating algorithm is programmed with the Matlab software andrun throughout the analysis procedures. Results show that more concrete temperature stress can be transferred to reinforcement with slower temperature variationand lower restraint degree during long-term loading periods. The relationship between restraint degree and concrete restrained stress reduction ratio has been developed.
