Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The exact prediction of creep is of great significance to the simulation of the stress field of concrete creep. As the limitation of the current prediction model of creep, by considering the characteristic of the concrete material, the available test data and the pertinent models abroad, the creep coefficient formulae is obtained. In the creep prediction of the high performance concrete, all the influencing factors are quantified, while the calculation is easy and convenient with good fitting accuracy. According to the fit of the creep degree, the implicit method is usually used in the calculation of creep stress field, and based on which, the creep coefficient formulae are established in this paper and used in the strain increment calculation, at the same time, the finite element expression to calculate the creep stress field with creep coefficient is deduced.
