Steel and steel-concrete composite structures in seismic area: advances in research and design. The Research Project RP3 of the ReLUIS-DPC 2014-2018. Activity carried out during years 2014-2016
No full textThis book collects the main outcomes of the research activity carried out within the line “Steel and Steel-Concrete Composite Structures” of the ReLUIS project 2014-2016 (Italian Civil Protection research project), which was chaired by Raffaele Landolfo and Riccardo Zandonini. Ten research units were involved in the scientific programme coming from the following Universities: Napoli “Federico II”, Salerno, Pisa, Sannio, Marche, Campania “Luigi Vanvitelli”, Chieti-Pescara “G. d’Annunzio”, Trento, Trieste and Genova. The research line was mainly devoted to the development of innovative approaches for the design of steel and steel-concrete composite buildings. Starting from the outcomes achieved during the previous ReLUIS project, novel results were obtained in the last years that are herein presented considering the four main investigated area, which are: steel and steel composite beam-to-column joints, conventional steel and steel-composite buildings, non-conventional steel buildings, steel and steel-composite bridges

No full textpp.67-79Sui margini del famoso codice Parisinus Latinus 5690 (che contiene, oltre a Tito Livio, Ditti Cretese e Floro), fastosamente illustrato, Landolfo Colonna prima e Francesco Petrarca poi lasciarono i segni delle loro letture. Petrarca, e in parte Landolfo, utilizzano i margini del codice parigino per deporvi considerazioni personali suscitate dalla personale lettura del testo, siano esse considerazioni e reazioni attualizzanti, che istituiscono un confronto tra l’antico e il presente, e instaurano un dialogo con l’autore, o siano appunti in vista di scritture storiografiche proprie. Ma Landolfo si è applicato a riempire i margini delle prime carte liviane del suo prezioso manoscritto ricopiando ampi stralci del commento di Nicola Trevet, particolarmente brani relativi alla leggenda di fondazione, alla legislazione antica e alle antiche magistrature.In the margins of the famous and sumptuously illustrated codex Parisinus Latinus 5690 (which contains, in addition to Titus Livius, Dictys of Crete and Florus), both Landolfo Colonna and later Francesco Petrarca left, as it were, their trace. Petrarca, and partly Landolfo, used the margins of the Parisian codex to comment upon the text as they read it: their remarks range from thoughts and reactions which establish a comparison between antiquity and their own time, and set up a dialogue with the ancient author, to notes taken in view of composing their own historiographical works. Landolfo devoted himself to filling the margins of the first Livian pages of his precious manuscript by copying extensive excerpts from Nicola Trevet’s commentary, in particular with passages concerning the foundation legend, ancient law and the ancient magistracies

Florence, 1427.Le marchand Landolfo Ruffolo, de Ravello en Calabre, ayant très mal vendu sa marchandise à Chypre, vend son navire, en achète un plus léger et se fait corsaire. Il a déjà un butin considérable quand il est à son tour attaqué, pillé et retenu prisonnier par les Génois. Mais la " caraque " sur laquelle ils l’ont embarqué se brise sur un récif ; il surnage, cramponné à une caisse qui flotte, est recueilli sur le rivage de l’île de Gulfe par une brave femme qui faisait sa lessive, constate que la caisse contient de magnifiques pierreries et rentre dans son pays plus riche qu’il n’en était parti
Refurbishment of the 80.000 m3 Napoletanagas gasometer
No full textThe term gasometer (or gasholder) was coined in the late eighteenth century by the Scottish engineer William Murdoch [1], inventor of gas lighting. Although the term literally means “gas meter” (a meter for measuring the amount of gas), it is commonly used, perhaps improperly, to indicate a structure conceived with the purpose of storing the town or illumination gas. In the past, these tanks were used to accumulate the town or illumination gas, which was produced in principle by the destructive distillation of coal. With the spread of natural gas in the second half of the twentieth century, the use of town gas is disappearing and the gasometers gradually lose their function. Nowadays, the gasometers are, in some cases, constructions of significant historical and cultural interest, belonging to the so-called “industrial archeology” and therefore deserve to be the subject of structural recovers and functional conversions [2]. The paper illustrates the refurbishment design of the 80.000 m3 gasometer, which is part of the Napoletanagas’s settlement of Via Benedetto Brin in Naples
Rotation capacity and overstrength of steel beams: evaluation of prediction models
No full textThe ductility is the structure’s ability to sustain large deformations in plastic range without
considerable loss of strength. The design concept based on the ductility properties of structures is
the principle method to assure for an appropriate structural behavior against strong ground motions.
The capacity to predict required and available ductility under severe loads is a key-point in
earthquake design. The actual progress in this problem is given by the possibility to prove the
ductility of the structure at the same level as for rigidity and strength. Unfortunately, in present
design specifications, there are only vague provisions relating to the evaluation of the structure
ductility, mainly based on cross-section classes. However, the actual ductility is affected by the
properties of full member [1]. In this regard, the knowledge of the rotation capacity and flexural
ultimate resistance of the steel member is of prime importance for an appropriate application of
hierarchy criteria in seismic design of structures [2]. In this paper, a critical review of the existing
prediction models for the rotation capacity and flexural overstrength factor for the steel members
with a wide range of cross-section typologies is presented. Moreover, the description of rotation
capacity and overstrength factor in current design codes is discussed comparatively
