Abstract:
Having in mind the social and economic importance that dams have in Brazil and the large investments made in relation to these structures, the objective of this work is to contribute to the study of these structures, through developing a program in MATLAB™™ language for stress analysis in concrete gravity dams. The routines developed allow usual verifications in dam projects, considering the action of silts and earthquakes stands out and also the variation of the geometric parameters and physical properties of the dam. The earthquake analysis follows two methods the PseudoStatic method (Westergaard Method) and the Pseudo-Dynamic method (Chopra Method). Before presenting the subroutines and the program’s functions, these methods are briefly discussed and a validation of stress results are made using CADAM 2000. Additional analyses are presented in reference to program’s potentialities and the conclusions.
