Abstract

Sunshine one of the most severe factors makes great effects on the mass concrete construction, especially on larger reinforced concert silo. In order to calculate the temperature distribution of the reinforced concrete silo subjected to the solar radiation, an easy-to-use tool is required for a transient analysis. As the first step of this paper, large-scale finite element software ANSYS is chosen as a basic platform. Further, the ANSYS Parameter Design Language (APDL) is adopted to establish a program to predict the nonlinear temperature distributions in circular reinforced concert silo in case of the solar radiation based on the experimental data and the heat transfer theory. Finally, the effect of the solar radiation, the geographic location as well as geometrical dimensions is investigated. The results clarity the distribution characters of the temperature. Besides, computational and experimental results are compared. The results indicate that sunshine nonlinearity temperature different can reach up to 10.2℃. As a result, attention should be paid to such temperature effect on the circular reinforced concrete silo.
