Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) combined with steel rebars, subsequently called R-UHPFRC, is a promising building material implying a novel technology for the improvement of concrete structures. Steel rebars enhance effectively th ...
In unreinforced masonry (URM) structures vertical walls are connected by horizontal spandrel elements. Spandrels have been subjected to extensive damage during earthquakes and are often the first elements within a URM building to crack or fail. If URM buil ...
The automatic generation of elastic-plastic stress fields (EPSF) for structural concrete members by means of the finite element method has been demonstrated as a suitable approach for the design and assessment of D regions. This methodology allows accounti ...
The spatiotemporal evolution of stress state is analyzed during the 2009-2010 Slow Slip Event (SSE) of Guerrero, Mexico, based on the kinematic inversion results and using an integral expression for stress changes. A linear slip weakening behavior is gener ...

The larger structures are, the lower their mechanical strength. Already discussed by Leonardo da Vinci and Edme Mariotte several centuries ago, size effects on strength remain of crucial importance in modern engineering for the elaboration of safety regula ...
The strengthening method characterized by the application of composite grid reinforced mortar layers onto the surface of masonry walls is a quite new technique and, thus, still requires deep experimental and numerical investigation. This strengthening tech ...
The experimental study introduces an unload-induced direct-shear model to investigate the frictional slip of a layer of simulated granular gouges induced by the combination of a decreasing normal stress and a constant shear stress. A frictional equilibrium ...
Quasi-static cyclic tests on reinforced concrete (RC) walls have shown that shear deformations can constitute a significant ratio of the total deformations when the wall is loaded beyond the elastic regime. For slender RC walls that form a stable flexural ...
In codes the drift capacity of unreinforced masonry (URM) walls is often estimated as a function of the failure mode and the aspect ratio. The empirical relationships are based on results from quasi-static cyclic tests on single URM walls, which were teste ...
