In this article, an analytical model is presented for the simulation of the thermal behaviour of dams that are subjected to environmental thermal action during service. The method of solution adopted, as well as the ...

Responding to the Agenda 2030 requires the action of a wide range of stakeholders, from local to regional stakeholders. These stakeholders include governmental bodies, but also other actors such as citizen associations or ...

O betão auto-compactável reforçado com fibras (BACRF) surge como uma consequência natural da tentativa de reunir num único material as vantagens associadas aos betões auto-compactáveis (BAC) e aos betões reforçados com ...

Decision support tools based on multi-attribute analysis involve the use of different types of variables. These variables are aimed at providing a framework that allows preferences to be quantified. This is particularly ...

The intercalation of polycarboxylate based superplasticizers (PCE) into montmorillonite clay (MNT) is arranged preferably by two types of absorption conformations: one-to-one conformation and bridging conformation. A third ...

The most singular characteristic of pervious concrete is its interconnected porosity that allows water to flow through at high rates. The objective of this paper is to develop and validate an advanced DEM-CFD model to ...

A diffusion–reaction numerical model is proposed to simulate the response of concrete exposed to external sulfate attack. Diffusion properties are modified based on the strain reached and the ratio of porosity filled by ...

La aparición de normas específicas para el empleo del Hormigón Reforzado con Fibras es, sin lugar a duda, una herramienta clave que proporciona al proyectista un mayor margen de confianza como solución estructural. Actualmente ...

La acción de las armaduras convencionales y de las fibras es complementaria a efectos de evitar la rotura frágil del hormigón. Las fibras, en tipo y cuantía adecuada, garantizan una clara responsabilidad estructural. Éstas, ...
