Abstract


Based on the existing theory of heat conduction and the rules concrete shell and irregular concrete shell structure of the temperature effect on the field, temperature stress , concrete shrinkage and creep research analysis , the main contents are as follows : on analysis of temperature field theory and the temperature effect of the concrete structure in the temperature effect , the shell structure of the temperature field of finite element theory is introduced and elaborated creep and shrinkage of concrete and concrete structure temperature effect . 2 , using ANSYS finite element analysis program , rules shell during the simulation analysis of temperature field under temperature effect , rules spherical shell under different temperature patterns of temperature effects and the same temperature mode different geometric parameters temperature stress and deformation analysis , comparative study of the different temperature effects on the impact of the rules spherical shell and rules of the radius of the spherical shell thickness , vector high sensitivity of the temperature effect . 3 , on the basis of the analysis in the rules shell temperature effect , using ANSYS finite element analysis program temperature effects during the use of the the irregular concrete shell engineering analysis study , by the thermal stress and deformation and rules spherical shell under the same temperature mode a comparative study has been the irregular concrete shell structure in the temperature under the general law , and proposed to simplify handling irregular temperature effect of the concrete shell structure ideas for engineering staff . Finally, a brief discussion of the direction for further work .
