The exact prediction of creep is of great significance for the simulation of the stress field of concrete creep. To overcome the limitation of the current prediction model of creep, pertinent models abroad are referred and adopted so that other factors can be controlled under standard state but only the creep varies to evaluate the feasibility of the prediction model with current characteristic of concrete materials and available test data. In the prediction of creep of high performance concrete, any influencing factor can be quantified, therefore, a large number of test data are not required. It was also observed that the defects that factors pointed out were common in the prediction model of concrete. The calculation was simple and convenient and achieved a higher accuracy. In the calculation of creep stress field, the creep was calculated according to fitting creep degree. Based on this, this paper established the creep coefficient formulas for the calculation of strain increment, and deduced the number of finite element expressions which were used to calculate the creep stress field with creep coefficient. |
