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.
