Abstract
Thelimitanalysisofdry-masonryblockstructureswithnon-associative Coulomb friction is formulated as a Mixed Complementarity Problem. After highlighting some of its peculiar features, such as the lack of uniqueness of the collapse multiplier, a fixed-point based algorithm is presented for constructing a solution, obtained by iteratively solving straightforward associative limit analysis problems. Supported by the comparison with benchmark problems, the resulting procedure is proven to be able to predict the collapse multiplier of masonry block structures with accuracy, robustness and effectiveness.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
