摘要：
In this work it is presented a 3D finite element program (DamDamage1.0), developed using MATLAB, for the non-linear analysis of concrete arch dams under static loads, aiming to assess the structural safety. The non-linear calculations are performed based on an iterative numerical method using a stress-transfer technique (considering the redistribution of unbalanced stresses), and simulating the concrete's behaviour up to failure with a constitutive damage model using 2 independent damage variables: d(+) for tension and d(-) for compression.
