Comportamiento a tempranas edades de elementos de hormigón con restricción externa total
(2011)
Text en actes de congrés
Accés restringit per política de l'editorialDurante las primeras edades del hormigón se producen deformaciones termo-higrométricas las cuales, si son restringidas, sobre todo por coacciones externas, producen tracciones que pueden fisurar el hormigón. Un ejemplo ... -
Computational modeling of high-performance steel fiber reinforced concrete using a micromorphic approach
(2013-12)
Article
Accés obertA finite element methodology for simulating the failure of high performance fiber reinforced concrete composites (HPFRC), with arbitrarily oriented short fibers, is presented. The composite material model is based on a ... -
Development and assessment of a modified ζ-method for deflection control of two-way slabs
(Féderation Internationale du Béton (fib), 2021)
Text en actes de congrés
Accés restringit per política de l'editorialDeflection control of two-way slabs is a very complex task considering their possible geometries, structural systems, reinforcement layouts and loading histories, as well as the large number of influencing parameters and ... -
Enhanced domain decomposition techniques for the modeling of softening materials
(2009)
Text en actes de congrés
Accés restringit per política de l'editorialIn this study a FETI: Finite Element Tearing and Interconnecting [1] technique is adopted and exploited for the efficient and accurate modeling of softening materials such as concrete and rock. A fie scale analysis in which ... -

Extension of the ζ‐method for calculating deflections of two‐way slabs based on linear elastic finite element analysis
(Wiley (John Wiley & Sons), 2021-06)
Article
Accés obertDeflections are among the most complex aspects of reinforced concrete behavior. Furthermore, deflection control is increasingly a governing criterion in design, especially in the case of two‐way members such as flat slabs ... -
Meso-scale modeling of concrete: a morphological description based on excursion sets of Random Fields
(2015-05)
Article
Accés obertIn view of the significant impact of thin scale heterogeneities in regards with the macroscopic response of concrete (and generally speaking of heterogeneous materials), a particular effort is dedicated to morphological ... -
Shear shell formulations in finite element modelling: software implementation issues and feasibility studies
(2016-01)
Report de recerca
Accés restringit per política de l'editorialModels for beam and shell elements allow for relatively rapid finite element analysis of concrete structures. This project involves the partnership of TNO DIANA BV, TU Delft and Rijkswaterstaat (Ministry of Infrastructure ... -
Simulació numèrica d’assaigs de tracció indirecta pel formigó en massa
(Universitat Politècnica de Catalunya, 2008-02)
Projecte Final de Màster Oficial
Accés obertEl que pretén aquest projecte, doncs, és fer la simulació numèrica de l’assaig de doble punxonament pel cas de formigó en massa. De la mateixa manera, també es farà la simulació d’un altre assaig de tracció indirecta: l’assaig ... -
Steel fibre reinforced concrete two-way slab: evaluation of structural response under uniformly distributed load
(Féderation Internationale du Béton (fib), 2021)
Text en actes de congrés
Accés restringit per política de l'editorialThe continuous study of the mechanical properties of fibre reinforced concrete (FRC) along with development of new fibre types and enhanced concrete mixes demonstrated adequate bearing capacity of the material and its ... -
Trends and perspectives in non-linear analysis of concrete structures under complex three-dimensional load combinations
(Civil-Comp Press, 2010)
Text en actes de congrés
Accés restringit per política de l'editorialIn this paper two different modelling techniques are presented and applied to nonlinear analysis of concrete structures considering B-regions and D-regions. A cross-section model capable of considering 3D phenomena and ...
