SISTEMA A PORTALE PER LA REALIZZAZIONE DI DISPOSITIVI PER LA DISSIPAZIONE DI ENERGIA PARTICOLARMENTE ADATTO PER LA PROTEZIONE SISMICA DELLE STRUTTURE PORTAL SYSTEM FOR THE REALIZATION OF DEVICES FOR ENERGY DISSIPATION PARTICULARLY SUITABLE FOR SEISMIC PROTECTION OF STRUCTURES
DESCRIZIONE DESCRIPTION
Lo schema globale di riferimento- è-quello del portale continuo (fig.1 e 2): due piedritti, incastrati al punto di vincolo, tra loro paralleli, ed un traverso, convenientemente più rigido e resistente, in grado di trasferire la sollecitazione da un piedritto all'altro. The overall reference scheme - is that of the continuous portal (fig. 1 and 2): two piers, interlocked at the constraint point, parallel to each other, and a crosspiece, conveniently more rigid and resistant, able to transfer the stress from one pier to another.
Durante lo spostamento vincolare imposto alle estremità incastrate dei piedritti questi saranno soggetti ad uno stato flessionale uniforme, agente nel piano del portale. Convenientemente, per avere una uniforme distribuzione della deformazione, i piedritti saranno a sezione uniforme per tutta la lunghezza. La geometria della sezione e la distanza tra i piedritti condizionano la forza assorbita, mentre la lunghezza dei piedritti determina la capacità di spostamento, sia in regime elastico, che plastico, e quindi la conseguente duttilità del sistema. During the constraint displacement imposed on the wedged ends of the piers these will be subject to a uniform flexural state, acting in the portal plane. Conveniently, in order to have a uniform distribution of the deformation, the uprights will have a uniform section along the entire length. The geometry of the section and the distance between the piers affect the absorbed force, while the length of the piers determines the displacement capacity, both in elastic and plastic conditions, and therefore the consequent ductility of the system.
il traverso, a sezione convenientemente maggiorata, può limitarsi alla sola funzione di elemento di collegamento tra i piedritti e di trasferimento dell'azione flessionale da un estremo all'altro secondo lo schema di trave a doppio incastro. the crosspiece, with a conveniently increased section, can be limited to the sole function of connecting element between the piers and transferring the flexural action from one end to the other according to the double interlocking beam scheme.
La configurazione a portale, semplice (fig. 1) o doppio contrapposto (fig. 9) o multiplo (fig. 10), essendo una configurazione jjiana, è oltretutto facilmente ricavabile da una piastra con riduzione dei costi di realizzazione e facilità di implementazione nei dispositivi di protezione, con particolare riferimento, ma non esaustivamente, ai controventi dissipativi, in questo caso, infatti, la configurazione piana consente di realizzare contestualmente e convenientemente anche il collegamento di coprigiunto nell’unione dell’asta di controvento con il corpo di collegamento ed ancoraggio all’elemento strutturale (trave, pilastro o nodo) facendo coincidere i collegamenti d’incastro dei piedritti con i punti di connessione tra le parti del controvento. The portal configuration, simple (fig. 1) or double opposed (fig. 9) or multiple (fig. 10), being a jjian configuration, is moreover easily obtainable from a plate with a reduction in construction costs and ease of implementation in the protection devices, with particular reference, but not exhaustively, to dissipative bracing, in this case, in fact, the flat configuration allows the joint cover connection to be made at the same time and conveniently in the union of the bracing rod with the connection body and anchoring to the structural element (beam, column or node) by making the interlocking connections of the piers coincide with the connection points between the parts of the bracing.
La differenza da altre soluzioni tecnologiche con piastre di coprigiunto lavorate in modo da ottenere parti deputate alla dissipazione risiede proprio nella geometria del contorno che attiva una risposta prevalente per flessione. Il vantaggio più evidente di tale differenza risiede, quindi, oltre che nella possibilità di una più ampia casistica prestazionale, nel ridurre le lavorazioni al solo taglio lungo il profilo di calcolo, senza necessità di ulteriori lavorazioni di macchina utensile altrimenti necessarie per individuare e caratterizzare le zone di dissipazione. The difference from other technological solutions with joint cover plates machined in order to obtain parts dedicated to dissipation lies precisely in the geometry of the contour which activates a prevalent response by bending. The most evident advantage of this difference therefore lies, in addition to the possibility of a wider performance case, in reducing the machining operations to just cutting along the calculation profile, without the need for further machine tool machining otherwise necessary to identify and characterize the dissipation zones.
Con riferimento alle figg. 3, 5 e 6, si vede come in una convenzionale configurazione di controvento dissipativo, questo preveda nel percorso dell’asta (1), a fare un tutt'uno con questa, la collocazione del componente dissipativo e, quindi, solitamente ricorrendo a due coppie di piastre di giunto (2), il collegamento ai corpi (3) di aggancio alla struttura. With reference to figs. 3, 5 and 6, it can be seen how in a conventional dissipative bracing configuration, this foresees in the path of the rod (1), to make one with it, the placement of the dissipative component and, therefore, usually resorting to two pairs of joint plates (2), the connection to the bodies (3) for hooking to the structure.
Il presente trovato appare essere assai conveniente in termini tecnologici, economici, di realizzazione e di montaggio in quanto prevede che la stesse piastre (2) di giunto diventino (figg. 4, 7 e 8), mediante opportuna configurazione, anche sede della funzione dissipativa, con conseguente eliminazione del blocco intermedio specializzato ed evidente semplificazione del sistema nel suo complesso. Si manifestano, tra le peculiarità più evidenti, le seguenti: The present invention appears to be very convenient in terms of technology, economics, construction and assembly as it provides that the same joint plates (2) become (Figs. 4, 7 and 8), by means of an appropriate configuration, also the seat of the dissipative function , with consequent elimination of the specialized intermediate block and evident simplification of the system as a whole. Among the most evident peculiarities, the following are manifested:
- Graduabilità totale di rigidezza, resistenza e rapporto resistenza/rigidezza; - Total gradability of stiffness, strength and strength / stiffness ratio;
- Elevata duttilità; - High ductility;
- Semplicità di posa in opera e di sostituzione; - Simplicity of installation and replacement;
- Totale libertà nella configurazione del controvento (a diagonale semplice, a croce di S.Andrea, a V, a V rovescia, etc.) - Total freedom in the configuration of the bracing (simple diagonal, St. Andrew's cross, V, inverted V, etc.)
- Possibilità di miglioramento da controvento normale a controvento dissipativo in situazioni esistenti (è sufficiente che il coprigiunto venga conformato in modo da adattarsi alla situazione esistente). - Possibility of improvement from normal bracing to dissipative bracing in existing situations (it is sufficient that the coupling cover is shaped in order to adapt to the existing situation).
La piastra di giunto, o coprigiunto dissipativo, può presentarsi pertanto così come meglio raffigurato nelle fig. 9 rappresentando una possibile geometria di lavorazione atta a ricavare, nell'ingombro della piastra stessa, anche il sistema di dissipazione. Le altre possibili configurazioni saranno ovviamente funzione delle prestazioni di resistenza, rigidezza e duttilità che verranno richieste al controvento, o più genericamente al dispositivo, nel suo insieme. The joint plate, or dissipative joint cover, can therefore appear as best shown in figs. 9 representing a possible machining geometry suitable for obtaining, within the overall dimensions of the plate itself, also the dissipation system. The other possible configurations will obviously be a function of the strength, stiffness and ductility performances that will be required at the bracing, or more generally, from the device as a whole.
Con riferimento alle fìgg. 4, 5, 6, 7, 8 e 9, che rappresentano una possibile configurazione tra tutte quelle possibili, il coprigiunto dissipativo può essere dunque costituito da una piastra (4), di dimensione adeguate a svolgere la funzione di connessione tra l'asta (1 ) ed il corpo di aggancio (3) attraverso le barre (5) passanti nei fori (6) per serraggio dei dadi (7). With reference to figs. 4, 5, 6, 7, 8 and 9, which represent a possible configuration among all the possible ones, the dissipative joint cover can therefore be constituted by a plate (4), of adequate size to perform the function of connection between the rod ( 1) and the coupling body (3) through the bars (5) passing through the holes (6) for tightening the nuts (7).
Nella configurazione illustrata di fig. 9 in cui il portale è rappresentato doppio e simmetrico, le coppie di piedritti (8) sono collegate dai trasversi (9), mentre la zona di vincolo (10) è comune ai due portali contrapposti; il tutto può essere ricavato convenientemente per semplice taglio di materiale a partire dalla piastra intera. In the configuration illustrated in fig. 9 in which the portal is shown double and symmetrical, the pairs of piers (8) are connected by the transversals (9), while the constraint area (10) is common to the two opposite portals; the whole can be conveniently obtained by simply cutting the material starting from the entire plate.
L'impiego di tale tecnologia è stato indicato a titolo meramente esemplificativo nella realizzazione di controventi dissipativi, ma può ovviamente essere adattata alla realizzazione di dispositivi dissipativi di protezione sismica o di semplice vincolo elastico anche di altro tipo, con configurazioni anche più articolate di cui quella rappresentata in fig. 10 mostra un modo per massimizzare le prestazioni mediante una possibile impostazione in parallelo. The use of this technology has been indicated purely by way of example in the realization of dissipative bracing, but it can obviously be adapted to the realization of dissipative devices for seismic protection or simple elastic constraint also of another type, with even more articulated configurations of which that represented in fig. 10 shows a way to maximize performance by a possible parallel setting.
