This research explores the mechanical behavior of dry-joint masonry subjected to combined shear–torsion–bending loading via the discrete element method (DEM), which has not been thoroughly investigated in the literature. ...

A detailed modelling approach to represent masonry at the meso-scale is proposed, based on the discrete element method, considering the nonlinear behavior of the joints and the units. The fracture of units is represented ...

análise de cenários de rotura associados à fendilhação do betão requer a utilização de ferramentas computacionais que sejam capazes de lidar com o comportamento resultante da micro-fendilhação generalizada e/ou de ...

Concrete gravity dams are mass concrete structures, often built on rock mass foundations, conceived to rely upon their weight for stability. To prevent sliding, these structures are usually keyed/embedded into the foundation, ...

Circular/spherical rigid particle models that were initially applied to rock fracture studies were not able to match the ratio of the compressive strength to tensile strength that occurs in rock. In addition, the predicted ...

Use of SSHM data for dynamic behaviour analysis and damage detection on large dams. The cases of Cabril dam and Cahora Bassa dam

This paper is focused on the study of the dynamic behaviour of two large arch dams, and it presents some innovations for the improvement of Seismic and Structural Health Monitoring (SSHM) systems for dams. The work describes ...
