How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Corrosion reduces the area of reinforcement steel, affects its mechanical properties, the bond properties, and produces concrete cracking. Thus, reduction of the bearing capacity and stiffness, increments of deflections and redistribution of stresses and internal forces, in statically indeterminate structures, take place. In addition, the efficienc...

Shear in beams and punching shear in slabs, is a long-time hot topic for design and safety evaluation. Due to the brittle behavior in shear of the reinforced concrete (RC) and prestressed concrete (PC) members, the assessment of existing structures must be carried out using reliable models, and, if possible, models based in the mechanical principia...
Article
A simplified mechanical model for the shear strength prediction of reinforced and prestressed concrete members with and without transverse reinforcement, with I, T or rectangular cross section is presented. The model, derived after further simplifications of a previous one developed by the authors, incorporates in a compact formulation, the contrib...
Conference Paper
O atual interesse pelo pré-esforço parcial é, em parte, motivado pelo recente desenvolvimento de novos códigos de dimensionamento baseados no desempenho. No entanto, o comportamento não linear dos elementos de betão parcialmente pré-esforçado (BPP) dificulta a sua aplicação na prática. Apesar dos progressos observados no estado de conhecimento, exi...

The Spanish Structural Concrete Code EHE‑08 was the result of a review in deep of the previous code EHE‑98. A large number of modifications aimed to adapt the Spanish Code to the current European Code framework and the current state of knowledge, to promote the improvement of the quality of the work without unjustified additional costs and to contr...
Article
In this paper, a theoretical study of the time-dependent behaviour of FRP (fibre reinforced polymer)-strengthened reinforced concrete (RC) cracked sections subjected to sustained loading is performed. Based on it, a simplified method for the calculation of long-term deflections has been proposed and verified with available experimental results. The...
Article
Long-term deflections, especially in cracked and slender R/C flexural members, may cause delayed damage in non-structural elements, so they must be accurately estimated at the design stage. The time-dependent response of cracked sections is complex, since creep and shrinkage produce a shift of the neutral axis, and the delayed curvature is signific...
