La centrale ENEL “Tifeo” di Augusta: ricerca e progetti per il recupero
2015
L'articolo presenta il lavoro, avviato nell'ambito del Dottorato di ricerca in Architettura/Progettazione Architettonica dell'Università di Palermo e conseguente alla stipula di una apposita convenzione con l'ENEL, finalizzato ad uno studio di fattibilità per individuare proposte qualificate e innovative per la riqualificazione e il riuso della centrale termoelettrica "Tifeo" di Augusta, ormai prossima alla dismissione. Lo studio mira ad individuare una strada concreta per la protezione di quest'opera di Giuseppe Samonà, legandola ad un possibile impatto positivo nell'ambito del difficile contesto in cui essa insiste. The recovery of the central "Tifeo" Augusta (SR), a valuable work of the …
Parameters affecting the fundamental period of infilled RC frame structures
2015
Despite the fact that the fundamental period appears to be one of the most critical parameters for the seismic design of structures according to the modal superposition method, the so far available in the literature proposals for its estimation are often conflicting with each other making their use uncertain. Furthermore, the majority of these proposals do not take into account the presence of infills walls into the structure despite the fact that infill walls increase the stiffness and mass of structure leading to significant changes in the fundamental period numerical value. Toward this end, this paper presents a detailed and in-depth analytical investigation on the parameters that affect…
Grid interaction and environmental impact of a net zero energy building
2020
Abstract The concept of Net Zero Energy Building (NZEB), as a grid-connected building that generates as much energy as it uses over a given period, has been developing through policies and research agendas during the last decade as a contribution towards the decarbonization of the building sector. However, since the most applicable and widely used renewable energy supply options are non-programmable, the large-scale NZEBs diffusion into the existing power grids can seriously affect their stability having a relapse on operation costs and environmental impacts. In this context, the study aims at performing the design of the energy systems to be used in the case-study through a wide numbers of…
Stan techniczny i wykorzystanie zabudowań po klasztorach skasowanych w guberni wołyńskiej w latach 1832–1853 w świetle raportu wołyńskiego gubernator…
2019
W trakcie XIX-wiecznych kasat klasztorów na obszarze cesarstwa rosyjskiego względy ekonomiczne stanowił istotny, może najważniejszy, ale niejedyny czynnik, uwzględniany przy podejmowaniu decyzji o zniesieniu domu zakonnego. Oficjalnie władze rosyjskie głosiły, że cały majątek klasztorny miał być wykorzystany na utrzymanie szkół oraz instytucji opiekuńczych i charytatywnych. W rzeczywistości przejęte ziemskie dobra klasztorne zasiliły skarb publiczny, a mienie z różnych powodów niezbywalne powiększyło majątek, pozostający w dyspozycji władz gubernialnych oraz Cerkwi prawosławnej. Władze długo nie doceniały znaczenia zabudowań poklasztornych. Dla większości z nich nie znaleziono nowego użytko…
The overall classification of residential buildings: Possible role of tourist EU Ecolabel award scheme
2012
Abstract The debate on the environmental performance of buildings and their classification is continuously rising and deeply involves all actors of the sector, from researchers to technicians and from owners to real estate managers. In the field, the EU has created a panel that is currently working on defining the criteria for attributing an Ecolabel award to a building. However, despite the enormous efforts made by administrative and academic institutions, a suitable and widely available scheme for operators to assess the environmental performance of a building is far from being established. To help provide a solution to the problem, the possibility of adopting the EU Ecolabel scheme estab…
Edifici scolastici tra gestione, riqualificazione e sostituzione: l’impegno per il Comune di Palermo
2014
Gli edifici scolastici svolgono un ruolo fondamentale, accogliendo le giovani generazioni in attività formative che ne condizionano il futuro. Essi sintetizzano i tempi in cui sono stati costruiti, assecondando però istanze contemporanee, dovendo adattarsi all’evoluzione sociale, pedagogica, normativa ed esigenziale. La pubblica amministrazione ha il compito di garantire la sicurezza, la salubrità, il decoro e l’efficienza energetica degli edifici scolastici: patrimonio collettivo, diffuso capillarmente ed eterogeneo per profilo tipologico-costruttivo e per stato di conservazione. Ciò richiede un approccio strutturato ma flessibile, modulabile su specificità che motivano diverse azioni: ges…
Le chiese della ricostruzione come fulcro identitario del quartiere: caratteri urbanistici e architettonici di due chiese post-conciliari della Sicil…
2014
The period that followed the Second World War marked a turning point for the building of our country. The compelling need, the desire to rebuild what had been destroyed and the desire to build structures using the techniques of contemporary manufacturing meant that the fifties and sixties were significant, also with regard to housing production, for the history of our country, from the point of view of both architectural and technical - constructive. The use of reinforced concrete, although already quite widespread before the war, he found the greatest statement both in the building residential use that in the sperimentation of large structures. The church buildings that were built in those…
Influence of wall-to-floor connections and pounding on pre- and post-diction simulations of a masonry building aggregate tested on a shaking table
2023
AbstractThis paper presents numerical simulations within the frame of the project SERA—AIMS (Seismic Testing of Adjacent Interacting Masonry Structures). The study includes blind pre-diction and post-diction stages. The former was developed before performing the shaking table tests at the laboratory facilities of LNEC (Lisbon), while the latter was carried out once the test results were known. For both, three-dimensional finite element models were prepared following a macro-modelling approach. The structure consisted of a half-scaled masonry aggregate composed by two units with different floor levels. Material properties used for the pre-diction model were based on preliminary tests previou…
Seismic response of steel frames with reduced beam sections
2003
This study concerns the effectiveness of weakening on the beams of fully and partially restrained connection steel frames in order to locate plastic hinges far from the joints. Two types of non-linear analysis, for geometry and constitutive law are developed: static pushover analysis, in which the structure is subjected to constant vertical loads and to horizontal loads linearly increasing up to collapse; and incremental dynamic analysis, in which the structure is subjected to uniformly scaled ground motions. Applications for four-bay frames with three and nine stories designed according to the EC3 code and for Italian 1st-category seismic areas are developed in order to evaluate the influe…
BRAZILIAN SOCIAL HOUSING POLICY: TOWARD A SUSTAINABLE FUTURE
2013
In the last decade, Brazil passed through several political and economic reforms that led to significant social changes, among which the reduction of the levels of inequality and extreme poverty. Nowadays considered one of the emerging economies, the country seeks to solidify its position through wide strategies aimed to propose decisive initiatives for a balanced social development, which are deeply affecting local architecture and urban planning. In this scenario social housing design has become, since the last decade, the mirror of a national policy that is implementing robust strategies to achieve high levels of growth. The paper provides an overview of the upgrades achieved in the fiel…
