A new concrete plastic-damage model with an evolutive dilatancy parameter
Poliotti, Mauro; Bairán García, Jesús Miguel (Elsevier, 2019-04-04)
Article
Accés obertTypical plastic-damage models for concrete use a constant dilatancy parameter. On problems sensitive to confinement and shear softening, this parameter needs ad hoc calibration to fit experimental observations. This makes ... -
A variable order framework for 3D nonlinear analysis of reinforced concrete frames under general loading
Poliotti, Mauro; Bairán García, Jesús Miguel; Moller, O. (Elsevier, 2021-09)
Article
Accés obertA framework for the analysis of three-dimensional reinforced concrete frame structures, capable of reproducing general failure modes, is presented. A force-based model which guarantees the equilibrium between nodal and ... -
Análisis de prestaciones en base a variables de impacto de un puente carretero bajo acciones sísmicas considerando incertidumbres
Möller, Oscar; Poliotti, Mauro; Ascheric, Juan P.; Valentini, Guido; Grossman, Sergio; Bairán García, Jesús Miguel (2022)
Text en actes de congrés
Accés obertLos puentes son sistemas de conexión de gran importancia socio-económica. Se presenta la evaluación del desempeño de un puente de vigas de hormigón pretensado existente ubicado en zona de alta sismicidad, donde los objetivos ... -
B-spline sectional model for general 3D effects in reinforced concrete elements
Poliotti, Mauro; Bairán García, Jesús Miguel (Elsevier, 2020-03)
Article
Accés obertIn this paper, an efficient sectional model for the nonlinear analysis of reinforced concrete elements sensible to 3D stress-components effects is presented. The classic plane-sections kinematic hypothesis is enhanced with ... -
Development and assessment of a modified ζ-method for deflection control of two-way slabs
Tošić, Nikola; Pecic, Nenad; Marí Bernat, Antonio Ricardo; Torres Llinàs, Lluís; Dragaš, Jelena; Poliotti, Mauro (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 ... -
Extension of the ζ‐method for calculating deflections of two‐way slabs based on linear elastic finite element analysis
Tošić, Nikola; Pecic, Nenad; Poliotti, Mauro; Marí Bernat, Antonio Ricardo; Torres Llinàs, Lluís; Dragaš, Jelena (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 ... -
A framework for 3D nonlinear analysis of reinforced concrete frames under general loading
Poliotti, Mauro (Universitat Politècnica de Catalunya, 2020-11-04)
Tesi
Accés obertModern guidelines for design and assessment of reinforced concrete structures under seismic and other extreme loads require nonlinear analysis. The complex structural response can be obtained by means of three-dimensional ...
