Influence of Reinforcement Placement on the Creep of Concrete

Abstract:

The creep of the concrete might cause comprehensive effect on the structure, such as stress redistribution and pre-stress relaxation. To better understanding the significant influence of the creep on the structure, the restriction of the reinforcement should be taken into account. In this paper, the creep of reinforced concrete was studied based on designed experiment with different concrete mixtures and reinforcement configurations. And Dischinger model was used to analysis the experiment results. It was found that, with the increasing of reinforcement ratio, the creep of all concretes could be reduced with a trend that the difference of the creep property between concrete mixtures would be delaminated by the reinforcement. And suggestion was proposed to modify the Dischinger model to better consider the influence of firm structure formed by rebar.
