Discrete-time multioverlapping controller design for structural vibration control of tall buildings under seismic excitation

2012

Published version of an article from the journal: Mathematical Problems in Engineering. Also available from the publisher:http://dx.doi.org/10.1155/2012/636878 In this paper, a computationally effective strategy to obtain multioverlapping controllers via the Inclusion Principle is applied to design discrete-time state-feedback multioverlapping LQR con- trollers for seismic protection of tall buildings. To compute the corresponding control actions, the proposed semidecentralized controllers only require state information from neighboring stories. This particular configuration of information exchange allows introducing a dramatic reduction in the transmission range required for a wireless imp…

Active-passive control strategy for adjacent buildings

2011

Author's version of a chapter in the book: 2011 Proceedings of the American Control Conference. Also available from the publisher at: http://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=05991059 In this paper, a control strategy to mitigate the vibrational response of adjacent buildings under seismic excitation is presented. The proposed strategy combines inter-building passive actuators with active actuators placed in the building stories. The main ideas are presented by means of a simplified two-building model; however, a semi-decentralized overlapping approach via the inclusion principle has been used to impose a proper information exchange structure suitable for wireless control of larg…

Semi-decentralized strategies in structural vibration control

2011

Published version of an article published in the journal: Modeling, Identification and Control. Also available from the publisher at: http://dx.doi.org/10.4173/mic.2011.2.2 In this work, the main ideas involved in the design of overlapping and multi-overlapping controllers via the Inclusion Principle are discussed and illustrated in the context of the Structural Vibration Control of tall buildings under seismic excitation. A detailed theoretical background on the Inclusion Principle and the design of overlapping controllers is provided. Overlapping and multi-overlapping LQR controllers are designed for a simplied five-story building model. Numerical simulations are conducted to asses the pe…

Sanctuaire de source, sanctuaire des eaux ou simple sanctuaire en milieu humide? Découverte d'un complexe cultuel antique à Magny-Cours (Nièvre)

2013

In advance of the future extension of the "technopole" and the construction of a service station in the district of Magny-Cours, the undertaking of two evaluations covering 15 hectares and 4 hectares, respectively, has revealed dense occupation of the site from the Neolithic period to the Middle Ages. The most important remains are associated with the Roman period and belong to a complex endowed with public buildings including several temples in an organised arrangement. This paper, preliminary to a larger study that will report on the whole of the site, is concerned specifically with the results obtained in a waterlogged area comprised within a zone that was excluded from the rescue excava…

Tres artistas en el exilio: Max Aub, Félix Candela y Josep Renau

2020

Three artists in exile focuses on the historical diaspora provoked by the Spanish civil war (1936- 1939), and how it influenced three prominent figures of the cultural scene of that period: the writer and typographer Max Aub Mohrenwitz (Paris, 1903-Ciudad de Mexico, 1972); the architect Félix Candela Outeriño (Madrid, 1910-Raleigh, US, 1977); and the artist Josep Renau Berenguer (Valencia, 1907-Berlín, 1982). They are the three protagonists of this article, who were simultaneously living in Mexico during the exile and who made notable contributions in the fields of arts and humanities (Max Aub), architecture (Félix Candela), and graphic design and photomontage (Josep Renau). While they were…

MAIFINITO

2014

Grandi quantità di edifici mai completati hanno prodotto speciali paesaggi extra-urbani, ma anche in alcuni casi interni a contesti urbani consolidati. Edifici che subiscono una condizione insita nel costruire: un atto che richiede una quantità di tempo – appunto di "costruzione" – dalla concezione alla realizzazione fino all’inizio del loro ciclo di vita, quindi mai immediato. Un edificio incompleto rimane lì dove è stato pensato e costruito, a volte per molti decenni, a differenza di un progetto, che come tanti, può rimanere in un cassetto. Il territorio di osservazione di partenza di questo libro è l’Italia del Sud e la Sicilia degli ultimi 50 anni, dove il fenomeno degli edifici "maifin…

STRUCTURE, ENVELOPE AND TECHNOLOGICAL INNOVATION The reinforced concrete in the construction of very tall buildings

2014

Until the second half of the nineteenth century, ie until the Industrial Revolution, the building structures played static function and also protective function. In the course of time separating the combination goes. The introduction of iron leads to a progressive "innovation" of building structures. The first application of iron in construction dates back to the mid-nineteenth century. They were first made with cast-iron columns and beams in iron and later with particular types of steel. The architecture of the iron is a true regeneration of the way of building, the cities are filled with sophisticated solid structures and slim at the same time, it enhances the transparency of glass, it in…

The influence of architecture, design and physical environment in residential buildings on cardiovascular disease – rationale and protocol for an ove…

2023

Introduction and Objective. Architecture and design solutions profile the environment and living conditions in residential housing and may have an impact on health. The aim of the study was to summarise all published systematic reviews (SRs) with or without meta-analysis (MAs), which assess the effect on cardiovascular disease (CVD) of the architecture, design and physical environment in residential buildings. Materials and method. This study presents the rationale and protocol of an overview of SRs. It was prepared according to Preferred Reporting Items for Systematic Review and Meta-analysis Protocols (PRISMA-P). Four bibliographical databases will be searched. Eligible SRs can include RC…

Viollet-le-Duc e la scoperta delle origini dell’architettura gotica

2017

Nella ricorrenza del secondo centenario della nascita, questo studio vuole mettere in evidenza alcuni aspetti ancora poco esplorati della formazione di Eugène Emmanuel Viollet-le-Duc, che hanno influenzato in modo fondamentale le sue ricerche. Ci si riferisce particolarmente all’interesse per la produzione artistica del Medioevo a cui lo studioso francese dedicherà le sue energie di ricercatore instancabile nel tentativo di trovare provenienze, derivazioni ed evoluzione dell’architettura gotica che rappresenterà anche lo stile ideale a cui riferirsi per collocarsi all’avanguardia della produzione architettonica del proprio tempo. Le naturali inclinazioni, la formazione liceale e la speciali…
