Analysis of Creep in Reinforced Concrete Based on Modified Burgers Model
In order to examine the effects of different reinforcement ratios on the creep properties of concrete, compression creep tests lasting 350 d were conducted on three types of specimens: plain concrete, 8 mm reinforced concrete, and 10 mm reinforced concrete. A modified Burgers model was developed by introducing a non-linear viscous element in series with the original Burgers model. The creep curves were obtained by fitting both the CEB-FIB (MC90) model and the modified Burgers model using the creep test datas of concrete with various reinforcement. The results indicate that reinforcement effectively mitigates concrete creep, and the mitigation effect becomes more pronounced with the increase of reinforcement ratios. Moreover, the modified Burgers model demonstrates superior accuracy compared to the CEB-FIP (MC90) model and provides better prediction for reinforced concrete creep.
