| Abstract: | According to the characteristics of mass concrete on silo′s foundation,temperature field and thermal stress is analyzed through the finite element software in this paper.The finite element calculation model in mass concrete of silo′s foundation is established based on ANSYS.In this model,meshing method and the problem of concrete elastic modulus variation with time are considered.Through the comparative analysis with engineering examples,it is proved that the model have a good effect in simulating analysis. |
