Article Preview

Based on the improved equation of concrete heat-generation rate and an improved calculation method of temperature stress, the temperature effect of concrete hydration heat is simulated successfully in ANSYS. Comparison between the numerical simulation results and test results of a scaled model of blast furnace foundation indicates that the calculated temperature field based on the improved equation and method is much closer to that of test than which obtained by the old equation and method. By using the stress superposition principle, the temperature-stress field can be calculated with considering the change of material behavior with temperature and time.
