Ossimoro - Oxymoron
2016
Può l'essenza dell'architettura trovare espressione i due sole parole? L'ossimoro sembra poter soddisfare questa domanda. La figura retorica greca diviene chiave di lettura e, al contempo, obiettivo da raggiungere attraverso il progetto. Forse più che un traguardo assoluto, l'ossimoro dà corpo a quella inquietudine che muta il razionalismo "tout court" in razionalismo esaltato, dove i principi logici sono scardinati dalla componente autobiografica. Can the essence of architecture be expressed in two words? The answer appears to provided by oxymora. The rhetorical Greek figure is both the key to interpret the project and the goal to be reached thanks to the project. More than an absolute goa…
Il complesso parrocchiale di San Gregorio a Cannatello (Agrigento)
2012
Nell'ambito dell'inchiesta che il "Giornale dell'Architettura" conduce sulla realizzazione de "Le chiese della Chiesa" a 50 anni dal Concilio Vaticano II, la rivista segnala quattro recenti progetti, sia italiani che di altre nazioni europee. Tra questi la Chiesa di San Gregorio ad Agrigento, della cui architettura contemporanea viene sinteticamente illustrato il progetto e documentata la sua realizzazione.
Old towns in “smart cities” between conservation and metamorphosis. Pending European Union guidelines
2014
In reflecting upon the role of environmental capital as represented by old towns in smart cities, the author reveals the consequences of re-plastering the facade of ancient buildings while emphasizing the resulting risk of globalization of historic districts. This is followed by a critical consideration concerning the active protection of old towns and their cultural typicality and geographical context, prerequisites for the development of specific guide-lines for the European Union. Explanation is also provided about how the restoration dynamics of the old towns are irreversibly changing the urban landscape in European cities. Strict regulations regarding the preservation of European old t…
Il Viadotto Akragas: demolizione o recupero strutturale?
2020
Architetti, ingegneri, urbanisti, ambientalisti e studiosi si confrontano, con idee fortemente contrastanti, sull’effettivo apporto del Ponte “Morandi” alla viabilità della città di Agrigento e al paesaggio della Valle dei templi: l’opera per rispondere ai minimi criteri di sicurezza ha bisogno di ingenti investimenti economici. Non un limitato restyling, bensì importanti interventi di consolidamento strutturale, tutti finalizzati a mantenere in esercizio il viadotto Akragas, almeno per alcuni ulteriori decenni.

2019
This paper investigates wave climate and storm characteristics along the Mediterranean coast of Andalusia, for the period 1979&ndash
Interaction between Longitudinal Shear and Transverse Bending in Prestressed Concrete Box Girders
2017
In box girder bridges, the quantity and distribution of reinforcement to be put in concrete elements of sections can be evaluated only by considering the deformation of the cross section in addition to the longitudinal analysis of the static scheme, establishing the entire state of stress of box sections. This leads to a need to evaluate the interaction between internal forces obtained by the global analysis and the ones obtained by the local analysis of the cross sections. The frame effect implies the elastic deformation of slabs and webs, whereas eccentrically applied loads lead to cross-section distortion with the loss of the box shape. Hence, the reinforcement is strongly influenced by …
Comparative experimental analysis on the compressive behaviour of masonry columns strengthened by FRP, BFRCM or steel wires
2017
Abstract In the last decade, several studies have investigated the application of Fibre Reinforced Polymer (FRP) wraps to masonry piers in order to provide a confinement effect and enhance compressive strength and ductility. Although this technique has proved to be quite effective, various drawbacks arise when organic resins are used to bind fibres. To solve these problems, different techniques have been developed to be used as alternative methods for enhancing the structural performances of weak masonry columns. Among these, the use of Basalt Fibre Reinforced Cementitious Matrix (BFRCM) wrapping, or the application of steel wires at mortar joints. This paper presents the results of an expe…
Analysis of multi degree of freedom systems with fractional derivative elements of rational order
2014
In this paper a novel method based on complex eigenanalysis in the state variables domain is proposed to uncouple the set of rational order fractional differential equations governing the dynamics of multi-degree-of-freedom system. The traditional complex eigenanalysis is appropriately modified to be applicable to the coupled fractional differential equations. This is done by expanding the dimension of the problem and solving the system in the state variable domain. Examples of applications are given pertaining to multi-degree-of-freedom systems under both deterministic and stochastic loads.
A reckoning with the maintenance of the built environment, a Sisyphean task
2023
Maintenance concerns most of the artifacts, referring simultaneously to the socio-cultural, technical and managerial spheres. Contemporary scenarios impose an overall rethinking, where key-topics such as tradition, consumerism, sustainability and digitization become pivotal in the search for suitable production models, between post-industrial and neo-craftsmanship, in order to have fresher references for the maintenance activities.
 In the construction field, maintenance is not limited to the objective of prolonging the duration of quality levels that only affect direct users, but also has important implications of a social and collective nature, in the case of both public and private …
Territorial Connection and Cohesion - The Case of Agrigento Inland Area
2014
The Europe 2020 strategy and the Horizon 2020 program can begin a real path about the role that the city will be able play for a new development. Usually, it is in the cities that are intensifying tangible and intangible social relations and, given that they focused almost 70% of the world population, it is clear that the city must begin to start any development scenario: the problems / opportunities related to the management of natural resources, energy to move. The culture is a «primary factor of urban creativity (...), the city's identity that has its roots the program schedule of history and extends its branches in the future» [4], awaiting a new model of development local self-sustaina…
