Abstract EN
Thermal cracking of massive concrete structures occurs as a result of stresses caused by hydration in real environment conditions.
The extended finite element method that combines thermal fields and creep is used in this study to analyze the thermal cracking of massive concrete structures.
The temperature field is accurately simulated through an equivalent equation of heat conduction that considers the effect of a cooling pipe system.
The time-dependent creep behavior of massive concrete is determined by the viscoelastic constitutive model with Prony series.
Based on the degree of hydration, we consider the main properties related to cracking evolving with time.
Numerical simulations of a real massive concrete structure are conducted.
Results show that the developed method is efficient for numerical calculations of thermal cracks on massive concrete.
Further analyses indicate that a cooling system and appropriate heat preservation measures can efficiently prevent the occurrence of thermal cracks.
