Many of modern life activities involve the risk of fire, explosions, and impacts. In addition, natural extreme events are becoming more and more common. us, robustness, the ability to avoid disproportionate collapse due to an initial damage, and resilience, the ability to adapt to and recover from the effects of changing external conditions, represent two important characteristics of current structures and infrastructures. eir definitions are reviewed in this paper with the aim of sorting and describing the different approaches proposed in the literature and in the international standards.

The catastrophic consequences observed after extreme events (flooding, earthquakes, vehicle impact, explosions, and fire) in transport and energy networks, as well as commercial and residential buildings, have significantly changed the public perception of risk regarding structures and infrastructure. Materials and structures are pushed to the limit in these conditions and given the fact that it is not always possible to provide an elastic response damage development must be considered and robustness becomes a precious characteristic.
Aging infrastructures represent a current engineering challenge. Huge budgets are necessary to keep their functionality and the lack of a proper and timely maintenance entails an increasing deterioration and therefore higher repair costs. Therefore, assessing the reliability of infrastructures becomes mandatory, with particular attention to the ones still in service even when their life limit has exceeded.
This paper aims to propose a new, fast and low cost method of condition rating for reinforced concrete bridges. This is based on visual inspection and non-destructive testing.
In contrast to many numerical methods, the eigenerosion approach yields a convenient description of fracture handled in the postprocessing part of a Finite Element Analysis (FEA). Its fully energetic formulation avoids the introduction of extra degrees of freedom to model fracture propagation. Following previous works on eigenerosion, in this publication, a modified formulation of eigenfracture it is introduced, where it is distinguished between compression and tension loaded state. This formulation has the advantage that it relates the crack propagation process only to tensile loading.
Design means to analyze, compare, manage and connect a large amount of data in order to develop, expand and materialize the starting idea, which was born to solve the initial problem. In this process, the engineer is the bridge of connection between the creative moment and its real implementation.
Dear all,
the International Journal of Structural Glass and Advanced Materials Research (IJSGAMR) is a peer-reviewed, open access journal which covers all aspects of theoretical and practical research of materials science.
In this paper, a simplified analytic model for the dynamic behaviour of railway catenary wire is presented. The model is discussed and validated with the help of numerical results obtained by a finite element code, for the case of a typical Italian railway installation. The simplified model is convenient from the computational point of view and is useful for sensitivity analysis. Some parametric studies have been developed by considering as free parameters the velocity and the distance of the train pantographs and looking at their effect on catenary dynamics.
