| Abstract: |
| The governing equations of the finite elements for the transient temperature field of concrete structures were expressed into t he st ate equations dispersing a spatial domain by the finite element method, regardin g th e element in which a cooling water pipe exists as a substructure, the other elem ents as common elements, and then were solved by the refined integral method. T hese results show the great advantages that the introduction of substructure, st ate equation and refined integral technology reduces requirement for computer storag e quantity, and enhances the temperature gradient accuracy off the water pipes. |
