The Analysis of Temperature Fields within Mass Concrete Structures by F. E. M.

A study on the protection against thermal cracks within mass concrete structures (I)

Abstract

Cracking within a mass concrete structure is caused mainly by a nonhomogeneous temperature field owing to cement hydration and ambient temperature.
Therefore, the analysis of this temperature field is necessary for crack protection.
Here, this analysis was made by a finite element method which is a very convenient tool for solving field problems.
In part (I), the F.E.M.analysis was applied to the unsteady state temperature field of a real structure and its accuracy was investigated.
The result was satisfactory except for small changes in the daily temperature.The efficiency of this analysis has been proved.
