The temperature field will generate thermal stress in the concrete cylinder. The thermal stress for mutative axial temperature in the steady ax-symmetric temperature field is analyzed
then the full analytical solution is obtained and the solution of undetermined coefficents is discussed using the property of power and trigonometric function. Based on the results of temperature testing by temperature sensor deposited beforehand and analytical solution
the numerical examples about the Φ200×550 mm
3
concrete cylinder are given by Matlab. By the analysis
the conclusions can be got as the follows: the distribution of thermal stress in concrete cylinder wouldnt change
the values of stress would be in the same order of magnitude
and the range of stress would increase 40 percents nearly in the steady axsymmetric temperature field as temperature has transformed from 100 ℃ to 120 ℃.
