    Abstract
  • In order to analyze shrinkage and creep effects of concrete exactly, based on the three-dimensional (3D) characteristics of shrinkage and creep, the shrinkage and creep effects of concrete under an ambient temperature environment were analyzed. A 3D shrinkage and creep effects mechanical model for concrete was established for varying temperature environments, and the corresponding calculation process was integrated with finite element analysis software ABAQUS. Then, the feasibility of the method and reliability of the results were verified using two examples. The results demonstrate that the maximum error of the model calculation is 8.2% and –7.1% for long-term deflection and concrete strain, respectively. The model suitably reflects the effect of temperature on creep strain, and the overall trend is consistent with the measured values. The maximum error is –20.5%, and this value decreases with the increase in age, the final error is 6.4%.
