Sub|structural FEM for the thermal effect of cooling pipes in mass concrete structures

;In this paper ,the sub|structural finite element method is adopted for analysing thermal effect of cooling pipes in mass concrete structures.The element which contains the cooling pipe is considered as a sub|structure and corresponding FEM formulas are derived.It is shown that by using the suggested method, the dimension of global stiffness matrix will not be increased when simulating the cooling pipes. Large and complicated practical engineering problems can thus be numerically dealt with.
