Text en actes de congrés
Accés restringit per política de l'editorialThis paper presents a numerical study of Mallorca Cathedral carried out by means of a FE approach devised for the study of this complex historical construction. Previous studies, including inspection and historical research, ... -
Creep and shrinkage effects in service stresses of concrete cable-stayed bridges
(2014-04)
Article
Accés restringit per política de l'editorialMost of the methods presented in the literature to define the target service stresses (Objective Service Stage, OSS) of cable-stayed bridges rarely include the time-dependent phenomena effects. Nevertheless, especially in ... -
Creep deformation in metallic glasses: a global approach with strain as an indicator within transition state theory
(Elsevier, 2024-03-01)
Article
Accés restringit per política de l'editorialWithin the framework of transition state theory, the isothermal creep behavior of metallic glasses is elucidated through a unique global approach, where the topological state is exclusively linked to measured strain. Our ... -
Creep of concrete with substitution of normal aggregate by recycled concrete aggregate
