A new FEM approach for FRP-strengthened RC frames

2017

Owing special mechanical properties has made Fiber Reinforced Polymer (FRP) as one of the best strengthening materials for Reinforced Concrete (RC) structures. The effect of externally applied FRP sheets on RC elements has been the topic of many experimental investigations. On the other hand, simulating the behavior of RC structures strengthened by means of externally bonded FRP sheets is yet to be scrutinized. In this work, a new Finite Element (FE) procedure for inelastic analysis of RC structures has been enriched to account the presence of externally bonded FRP sheets on RC sections. The proposed FE procedure works in the framework of lumped plasticity. It is able to identify the exact …

RC Masonry infilled frames: Experimental results and development of predictive techniques for the assessment of seismic response

2014

La presenza di tamponamenti in muratura all’interno delle maglie di strutture intelaiate induce, in presenza di azioni laterali, una sostanziale modificazione della risposta globale rispetto a quella dei telai nudi in termini di rigidezza, resistenza e capacità di spostamento. La tesi presenta i risultati di una campagna sperimentale su telai tamponati con diverse tipologie di muratura soggetti a prove di carico cicliche. Successivamente viene proposto un criterio per la modellazione semplificata del comportamento ciclico attraverso un macromodello a puntone diagonale equivalente. Una ulteriore indagine numerica è eseguita per valutare l'entità degli effetti locali dovuti all'interazione fr…

Sine cura. Verso il ri-ciclo dell'architettura del secondo Novecento

2019

Gli argomenti discussi nel saggio interrogano il destino che il Codice dei Beni Culturali (2004- 2011) determina per le opere del secondo Novecento. Nella costruzione del futuro di questi manufatti, che per funzione, tecnologia e cicli d’uso sono spesso segnati dall’obsolescenza e dall’abbandono, le ambiguità e le incongruenze delle attuali procedure legislative sollecitano profondamente il ruolo culturale delle esperienze di ricerca che usano metodologie meta progettuali. Il confronto fra alcuni casi italiani ed altri europei rimarca il ruolo del progetto nella costruzione di una prospettiva di tutela trasformativa per il costruito del secondo Novecento. Nel quadro di azione marcato dall’o…

Settore ICAR/14 - Composizione Architettonica E UrbanaThe essay questions the future's possibilities to operate on the buildings of the second half of the twentieth century according to the Italian Code of Cultural Heritage (2004-2011). When arguing how to encourage the re-use of these artifacts which are often marked by short-life technology cycles obsolescence and abandonment the ambiguities and inconsistencies of current legislative procedures deeply stress the cultural role of research experiences that use project-oriented methodologies. The comparison between some Italian and other European cases highlights the role of a design approach in the construction of a transformative protection perspective for the built matter of the second half of the twentieth century. In a framework aiming to encourage a reconciliation between the recent built environment and the new paradigms of sustainability and circular economy architecture must recognize re-cycle practices as a main theoretical and procedural node. To modernize the late Modern built environment with contemporary construction components is not simply a matter of technical knowledge and expertise: but a theme with theoretical density aesthetic and ethical values. The architectural project in this field today must ask for greater congruence between the bureaucratic and administrative levels and the real consistency of this corpus. It is a matter of identifying strategies to equip it with capabilities meanings and contents remembering that demolition wastes have unsustainable environmental costs and uncertain results concerning the necessary new attribution of political and semantic meaning that these places await.

Viaggio nel dramma di un “contesto romano”: l’anfiteatro di Londinium. LE BUONE PRATICHE DELL’ILLUMINAZIONE

2012

James Turrell, uno degli artisti della luce più significativi della nostra epoca, definisce l’esperienza dell’immergersi in un pittorico e arcano mondo di luce, chiamandola “sentire con gli occhi”. Le nuove tecnologie ampliano le possibilità di servirsi della luce nell’arte e nella cultura. La messa in scena creata grazie all’illuminazione in movimento si traduce nella interazione fra spazi e colori, creando un’atmosfera capace di avvolgere profondamente chi la vive, con una spettacolarizzazione che provoca una percezione totalizzante nello spettatore.

Palermo si cura. Pratiche culturali di mutuo soccorso come risposta alle fragilità della città (post)pandemica

2023

In un quadro di riferimento in cui la crisi è globalizzata ma diseguale e in mancanza di un sistema di welfare capace di rispondere alle urgenze dei contesti e dei gruppi sociali più marginalizzati, una risposta ai nuovi bisogni sociali ed individuali è stata offerta da reti solidali e da pratiche di mobilitazione dal basso che svolgono un ruolo di agency territoriale, spesso indipendentemente o in assenza di Istituzioni. Nel contesto palermitano un impegno agito da una pluralità di soggetti culturali già attivi sul territorio, riuniti in un’assemblea pubblica (Palermo si cura), durante il periodo del primo lockdown hanno dato vita ad azioni di mutuo soccorso per rispondere all’emergenza ec…

Settore ICAR/21 - UrbanisticaIn a framework in which the crisis is globalized but unequal and in the absence of a welfare system capable of responding to the urgencies of the most marginalized contexts and social groups a response to the new social and individual needs has been offered by networks of solidarity and from bottom-up mobilization practices that play a role of territorial agency often independently or in the absence of institutions. In the Palermo context a commitment made by a plurality of cultural subjects already active in the area gathered in a public assembly (Palermo si cura) during the period of the first lockdown gave rise to mutual aid actions to respond to the economic emergency and social and offer a proposal to cure the fragility of the city based not on charity but on the claim of a political dimension of collective action. Starting from the analysis of initiatives such as "Un sorriso per Ballarò" and "Abbiamo un (bi)sogno" the contribution analyzes the role the incidence and the fragility of these experiences in providing answers - often filling gaps - to a general interest and how these processes of value creation can hopefully contribute to the construction of local government policies capable of addressing emerging issues.

E-LEARNING AND ART OF PROGRAMMING: A CONTEXT ORIENTED TO

2017

Coding or programming is very important for a number of tasks and this is true not only in problem solving but also in the computer science and over. Many skills have to be acquired before to have a high familiarity degree with this science. In the studies for methods of coding, students have a great problem for understanding on how to solve and to develop algorithms in a rational way, thus the expertise on how to solve and to develop algorithms is the most difficult to acquire for all students in whatever age. This paper introduces the prototype of a framework able to running in the web space and to be supported by different devices and browsers, useful to integrate a number of collaborati…

USER- AND CONTEXT-ORIENTED CRITERIA FOR ASSESMENT OF HIGH EFFICIENCY POLYGENERATION PLANTS FOR BUILDINGS APPLICATIONS

2013

The eligibility criteria adopted to assess polygeneration plants as “highly efficient” can play a determinant role in favouring or discouraging the market growth of polygeneration systems, especially for buildings applications where economic viability is often more difficult to achieve. Basing on the current European framework, in this paper the opportunity to adopt user- and context-oriented criteria is discussed. After having identified three buildings with different uses (a large hotel, a hospital and an office building), the optimal layout and operation strategy of a polygeneration plant serving each building is determined; then, ex-post processing of economic and energetic results is u…
