The integration of healing capsules into asphalt mixtures has demonstrated promising advancements in their intrinsic self-healing properties. However, the efficacy of this technology still requires further investigation. ...

A 3D spherical rigid particle discrete element formulation based on the Discrete Element Method, DEM, which has been used to model concrete, is described. The model has been shown to give a good agreement in terms of peak ...

Cracks propagating deep inside gravity dams can seriously affect their structural safety. Due to the potential catastrophic scenarios associated to the collapse of large concrete dams, it is a fundamental issue to ...

This paper presents the relevant monitoring data and the main results of the analysis and interpretation of the structural behaviour of Bouçoais-Sonim dam, a medium-size gravity concrete dam of 42.5 m high, during the first ...

Small concrete gravity dams are sometimes built using passive steel anchors to enhance their stability for the applied loads. It is important to assess the amount of internal tensile and shear forces resisted by the anchors ...

This paper presents the analysis, interpretation and prediction of the structural behavior of Cahora Bassa dam, which concrete is affected by a moderate ongoing swelling process, of the alkali-silica (ASR) type. To ...

A aplicação de modelos de identificação modal no domínio da frequência à análise dos resultados de ensaios de vibração ambiental efectuados no corpo da barragem do Cabril mostrou que, para além dos esperados picos espectrais ...

A barragem de Pretarouca, no rio Balsemão (serra de Montemuro, concelho de Lamego), tem 29,70 m de altura e 305 m de desenvolvimento. A albufeira tem 3,2 hm3, destinando-se a água a abastecimento público. A obra, construída ...

As barragens são estruturas que representam risco potencial elevado pois em caso de rotura podem causar perdas humanas e materiais importantes. Através da sua observação criteriosa e com recurso a modelos numéricos faz-se ...
