Research on Temperature Stress of Annular Super-Long Frame Structure by Finite Element Method

Abstract:

The temperature stress calculation of multi-storey structure is very complicated. Many researches have been taken for the frame structures with rectangular plane, but very few references about annular plane. Based on the ANSYS program, the structure temperature effect of a multi-storey reinforced concrete frame which plane shaped like the elliptic is analyzed in this paper. The overall temperature load and concrete shrinkage equivalent temperature are considered in the analysis. The results reflect that curvature has an apparent influence on the temperature stress of annular super-long structure. Besides, the structure temperature effects are studied on both cases of the structure with expansion joint and without it, which shows that reasonable installation of expansion joint can decrease the temperature stress of annular structure. The influence of structure member rigidity on temperature effect is also discussed by changing the size of the section; all of these could offer reference for engineering design.
