Shear design of high strength concrete beams in MRFs
2019
This paper presents the criteria for the shear design of high strength concrete (HSC) beams in moment resisting frames (MRFs). The formulation of an analytical model is provided for the case of beams with longitudinal reinforcement in the presence of transverse stirrups. The model is of additive type, in the meaning that the shear resistance of the beam is evaluated as the sum of several contributions. In particular, the contribution of concrete, longitudinal rebars, and transversal reinforcement are taken into account. Furthermore, for assessing the concrete contribution, a classical approach is followed, according to which two effects arise in the shear mechanism: the arc and the beam eff…
La porte Saint-André à Autun.
2013
National audience; Sous le règne d’Auguste, aux alentours du changement d’ère, quatre portes urbaines furent construites à Augustodunum : l’entrée tournée vers le nord-est a reçu son nom actuel lorsqu’on installa au Moyen Âge une église dédiée à saint André dans l’une des tours de flanquement de l’ancienne porte de ville. Cette réutilisation partielle de l’édifice antique, à une époque où l’enceinte romaine avait cessé d’être fonctionnelle, contribue à expliquer pourquoi cette porte monumentale est parvenue jusqu’à nous dans un état de conservation aussi exceptionnel.
Financer les murs de la ville dans l'Italie du Ier siècle avant J.-C.
2013
Les dernières décennies de la République romaine et les débuts du Principat voient nombre des villes d'Italie s'entourer de murailles. Pendant plusieurs années, les chercheurs se sont essentiellement interrogés sur les aspects militaires (securitas) et symboliques (dignitas) de ces structures considérables. Afin de cerner ce phénomène de manière plus précise, il convient désormais de chercher à restituer le cadre économique dans lequel les chantiers de construction de ces enceintes urbaines ont été mis en place.

The plant landscape of the Sicilian archaeological areas through the iconographic documentation of travellers and naturalists
2018
The landscape is commonly defined as the set of physical and historical-anthropological characters expressed by a territory. Our re-elaboration defines the landscape as the set of perceivable characters of a territory expressed in relation to the stratification of the occurred natural and cultural processes. The Grand Tour reports are one of the most effective means to fix at least one stage of evolution from the Sicilian landscape, before its further transformation. These reports provide often a stereotypical image of the landscape of the Island, in particular as regards the major archaeological areas subjected to particular attention by the cultured travellers. The authors summarize the c…
Rational vs historical reconstructions. A note on Blaug
2003
The paper focuses on Blaug's distinction between rational and historical reconstruction within the historiography of economics. Blaug's distinction is shown to be sterile and misleading and his definitions of no avail to clear thinking. Historical reconstruction (as defined by Blaug) is en empty box for reasons which are basically theoretical and not simply practical (as Blaug seems to hold). Moreover, Blaug's primary polemical target is Whig historiography and not rational reconstruction: the two concepts coincide only by means of an ad hoc definition. Blaug's criticism does not apply to other uses of the concept of rational reconstruction such as that proposed by Lakatos.
Il terremoto del 1542 in Val di Noto: i casi di Lentini e Siracusa, dalla gestione dell'emergenza al rinnovamento urbano
2012
All’interno del più generale quadro delle distruzioni e ricostruzioni di interi centri urbani o significative parti degli stessi conseguente al terremoto che nel 1542 colpì violentemente il Val di Noto, questo contributo analizza due casi studio di particolare interesse e chiaramente esemplificativi delle problematiche in campo, nonché delle strategie e modalità di intervento e dei processi di rinnovamento attivati dall’evento distruttivo. Nel caso di Lentini, le vicende conseguenti al terremoto agevolano la formulazione di un progetto di ricostruzione dell’intera città in altro sito che avrebbe soddisfatto anche esigenze di natura difensiva. Le opposizioni incontrate a livello locale fanno…
Event reconstruction algorithms for the ATLAS trigger
2007
The ATLAS experiment under construction at CERN is due to begin operation at the end of 2007. The detector will record the results of proton-proton collisions at a centerof- mass energy of 14 TeV. The trigger is a three-tier system designed to identify in real-time potentially interesting events that are then saved for detailed offline analysis. The trigger system will select approximately 200 Hz of potentially interesting events out of the 40 MHz bunch-crossing rate (with 109 interactions per second at the nominal luminosity). Algorithms used in the trigger system to identify different event features of interest will be described, as well as their expected performance in terms of selection…
<em>L’entramès de Mestre Vicent</em>: resplandor de la autoridad del predicador
2019
El presente artículo aborda múltiples aspectos, algunos inéditos, referentes a l’entramès de Mestre Vicent. Entre los objetivos del estudio descuella la reconstrucción virtual y documentada de aquel carro que, quizá albergando la primera representación de Vicent Ferrer, desfiló en Valencia a finales de 1414 con ocasión de la entrada real de Fernando I. Otras cuestiones de especial relevancia atañen a la autoría del programa iconográfico y al proselitismo que denotaba aquella estructura, cuyos máximos beneficiarios fueron el Trastámara y la propia ciudad. Metodológicamente, se subraya la complejidad que entraña ceñir la interpretación del entremés amparada exclusivamente en la literatura, má…
