Abstract
This paper discusses the results of measurement and analysis of thermal stresses in actual massive concrete block. The following can be obtained. (1) Stress meters, if installed properly to connect tightly with the surrounding concrete to be measured, can measure thermal stress with adequate accuracy for practical use. (2) If reliable data concerning the mechanical properties of concrete were to be available, thermal stresses of the same degree of reliability as stress meters can be obtained with embeddedtype strain gages using the evaluating method given in this paper. (3) The results of thermal stress analysis using 3-dimensional finite element method with the algorism developed in this paper, coincide good with the measurement results of thermal stresses in actual massive concrete block.
