Notes:
In the study of concrete-face dams it is essential to provide joint elements; otherwise the calculated stresses at the facing will be non-allowable. Three-dimensional joint elements must be simple so as not to increase in excess the CPU time. Seven non-incremental joint elements have been formulated or developed, and their relative advantages discussed. It is shown that quasi-linear or linear joint elements at the perimeter of the solid elements can have calculation advantages, specially for interfaces with ‘no tension’ resistance.A system of thin solid finite elements (FE) joints at the face may reproduce qualitatively the displacements and stresses, but not quantitatively. With a system of quasi-linear elements placed at the boundaries of the solid FE we have been able to predict correctly the displacements, strains and joint openings at Cethana concrete-faced rockfill dam.
