Strut-and-tie models provide a simple and rational way to design discontinuity regions in reinforced concrete structures. However, when it comes to three-dimensional concrete elements such as pile caps, enhancements are needed to ensure a reliable an

Elastic "shock" waves emanating from the wheel-rail interface of a train running at a speed close to one of the propagation velocities of the soil may cause great amounts of nuisances to the population. An integrated rigid body - FEM model has been c
