“…An advanced computational model has been utilized lately to analyse the structure including the effect of the construction process (Clemente, 2006;Roca et al, 2012Roca et al, , 2013. This first attempt to model the construction A c c e p t e d M a n u s c r i p t 4 process investigated the possibility of erecting the structure without the use of auxiliary members such as iron ties.…”

“…The locations of the ties as well as their dimensions and mechanical properties are defined according to the results of a photogrammetric survey. This information is used to update the FE model developed by Roca et al (2012Roca et al ( , 2013 with the aim of modelling the use of temporary ties during the construction process. A sequential FE analysis of the fourth bay is carried out to understand the structural role of ties in the intermediate stages of the construction.…”

This paper presents the analysis of the structure of Mallorca Cathedral taking into account the influence on structural behaviour of auxiliary iron ties used during the construction process. Recent studies have presented some hypotheses about the construction process of the cathedral. The present study complements the previous results by considering the use of auxiliary ties as temporary stabilizing device during the construction.Evidence of the use of ties during the construction has been recognized after a comprehensive survey. The study of the role of such ties and the effect of their later removal are studied by a FE analysis carried out on a representative bay of the structure. The study includes a time-dependent FE analysis after the removal of the ties to assess the long-term structural behaviour. The results of the numerical analysis are compared with the deformation trends identified by means of a recent monitoring campaign.

“…El presente trabajo mostrará el estudio constructivo de la catedral de Valencia y su análisis estructural, a partir de un modelo informático con E.F. (6). La manipulación de este modelo mediante la eliminación selectiva de arbotantes, diafragmas y/o refuerzos, genera cinco variaciones, cuyo análisis mostrará la función de cada uno de estos elementos estructurales.…”

.es (V. Llopis Pulido) RESUMEN Las características constructivas de la catedral de Valencia la convierten en un ejemplo representativo del gótico mediterrá-neo: reducida esbeltez, escasa diferencia de altura entre las naves y limitadas dimensiones de huecos.Estas características se explican a partir del presente trabajo donde se muestra un estudio constructivo y un análisis del sistema estructural frente a cargas gravitatorias y efectos sísmicos. En el análisis se utiliza el método por empujes incrementales (pushover) y el método no-lineal de modelo de daño. La función de arbotantes y diafragmas quedará patente con la modificación del modelo MEF que eliminará progresivamente cada uno de estos elementos constructivos.Los resultados muestran una suficiente capacidad resistente frente a un sismo con un período de retorno de 475 años que empeora si se considera de 950 años. Se evidenciará la necesidad de la continuidad muraria a través de los arbotantes que se convierten en auténticos muros diafragmáticos.Palabras clave: Gótico mediterráneo; análisis sísmico; pushover; modelo de daño; elementos finitos; período retorno.

“…In this work, the use of a single damage variable is justified by our aim to investigate fracture due to only tensile and shear stress states. In the general case, where damage due to compression may be critical, an equivalent damage model with two separate damage variables for compressive and tensile damage can be used (see Roca et al 2013, Petromichelakis et al 2014, Pelà et al 2014b, Saloustros et al 2015.…”

-This paper extends the use of crack-tracking techniques within the smeared crack approach for the numerical simulation of cohesive-frictional damage on quasi-brittle materials. The mechanical behaviour is described by an isotropic damage model with a Mohr-Coulomb failure surface. The correct crack propagation among the two alternative fracture planes proposed by the Mohr-Coulomb theory is selected with the use of an energy criterion based on the total elastic strain energy. The simulation of three benchmark problems of mixed-mode fracture in concrete demonstrates that the proposed methodology can reproduce the material's frictional characteristics, showing robustness, as well as mesh-size and mesh-bias independence.
