Complete 3D models of URM structures can be obtained assembling 2-nodes macro-elements, representing the non-linear behaviour of masonry panels and piers. This modelling strategy has been implemented in the TREMURI program with non-linear static and dynamic analysis procedures requiring limited computational loads. By means of internal variables, the macro-element considers both the shear-sliding damage failure mode and its evolution, controlling the strength deterioration and the stiffness degradation, and rocking mechanisms, with toe crushing effect. URM building models can be obtained assembling plane structures, walls and floors. Masonry arch bridges can be modelled and analysed through the macro-element approach, too.

Abstract
Complete 3D models of URM structures can be obtained assembling 2-nodes macro-elements, representing the non-linear behaviour of masonry panels and piers. This modelling strategy has been implemented in the TREMURI program with non-linear static and dynamic analysis procedures requiring limited computational loads. By means of internal variables, the macro-element considers both the shear-sliding damage failure mode and its evolution, controlling the strength deterioration and the stiffness degradation, and rocking mechanisms, with toe crushing effect. URM building models can be obtained assembling plane structures, walls and floors. Masonry arch bridges can be modelled and analysed through the macro-element approach, too.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
