Abstract
The authors of this work take again a very simple formulation for determining the load collapse multiplier for masonry structures, by a linear formulation founded on the classical limit analysis theorems. To draw the model as much as possible near to the real collapse mechanism, now it is supposed the formation of failure lines also along the diagonals of macroblocks, so introducing in the discretization process even triangular elements. Moreover, to underline the influence that the modality of texture of bricks or of stones has on the behaviour of a panel, the friction coefficient tgφo used for the horizontal interfaces is suitably increased along the diagonal and vertical interfaces of macroblocks.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
