Abstract :

Analysis of the double curvature concrete dams is accurate when the models are properly prepared and analyzed by three dimensional finite element. In this research, the double curvature concrete Bakhtiari dam is analyzed with the use of three dimensional finite element method. To this end, the ADSHAPE program which can model all kinds of dam body is encoded in the MATLAB program. Then, its output is given to encoded AD ANALYSIS program which can analyze three dimensional finite element dam body. For the accuracy and calibration the program, the model cantilever beam to define its result was employed. This method in all kinds of elements with different elements size and with different Gussian points is analyzed and the results are compared. The effect of charges of elements and Gussian points in the results will be considered. Then Bakhtiari dam is analyzed with regard to proper principle of mesh generation and accurate model and stress and deformations are studied. The results showed the acceptable accuracy of coded programs in modeling and three dimensional finite element analysis of Bakhtiari dam.
