Analysis of effect of reinforcement on concrete creep behavior

Considerable deformation generates when concrete is with long-term loading and creep is one of the most important time-dependent behaviors and needs to be paid enough attention. It is of great important to understand the workability and liability of structures under long-term loading. This paper presents a method for calculation of concrete stress and strain considering effect of reinforcement and factor of reinforcement ratio has been considered. Results show that concrete stress can be reduced to some extent when reinforcement is placed under long-term loading and a reinforcement ratio of 3% is favorable. In addition, a reinforcement impact factor is recommended to quantify effect of reinforcement on concrete creep behavior.
