BEGINNING\/END OF WORKS<\/strong>: 2003-2005<\/p>\n
The structure as a whole is composed of a reinforced concrete tower of tubular section with a diameter of 2.50 m and a total height of 47 m. The tower is placed, with its prominence, inside the shed destined to be the transmission site, therefore up to a height of about 5.0 m it is concealed from view.
The tower is equipped with five levels of terracing in metal carpentry. The horizons are equipped with tubular uprights arranged radially towards the outside of the tower itself in order to be able to place transmission dishes on them. The deck beams of these terraces are also arranged radially with respect to the center of the tower. Said beams are hinge-bound to the wall of the shaft, with a vertical tubular metal tie-rod connected to the reinforced concrete platform that has the static value of acting as an indirect end-bond for all four platforms. The connection between the shaft and the slab, with casting of the two components carried out in successive phases, consists of sleeves and bars, both threaded, for joining the reinforcements without overlapping.
Particular mention should be made of the study of the wind profile performed in the frequency domain; the determination of the wind profile was carried out in accordance with the regulations in force in Italy, while the aerodynamic analysis of the wind on the shaft (study of the shape coefficients) was performed in accordance with EC1 and the most recent bibliographies on the subject.
In this way it was possible to take into account, through the determination of Reynolds number, the roughness of the surface invested by the wind, the slenderness of the structure (height-diameter ratio) and the wind speed at each point examined. By doing so, it is possible to determine the shape coefficient which better captures the real behavior of the structure as a whole with respect to what is indicated in the Italian Norm in force.
It has been also carried out the dynamic analysis of the structure with the research of the first vibration mode in order to find the dynamic coefficient Cd for the structure. This research has been carried out with the help of the writings of Prof. Solari and allows to find the multiplier coefficient of the wind thrust due to the gust behavior of the same. This Cd value is introduced numerically as a multiplier of the wind load of static character. The tower foundation consists of a square plinth placed on drilled piles. The piles reach a depth of 26.0 m., penetrating into the gravel level present from 23 m onwards. Up to this height they cross silty-clayey-sandy layers which, also due to the presence of the water table, do not guarantee the required capacity of the piles. Non-destructive tests were also carried out on the piles by means of ultrasonic cross-hole in order to check the optimal realization of the piles in terms of both depth and compactness of the casting itself.
Finally, the execution of detailed calculations on the stability of the front of the excavation in the execution of the foundation plinth made it possible to avoid the costly construction of a bulkhead containment excavation, required in a hurried manner and without technical justification by the contractor.<\/p>\nPROGETTO DELLA TORRE CILINDRICA IN CALCESTRUZZO ARMATO PER TELEFONIA CELLULARE E TELECOMUNICAZIONI A MODENA<\/h3>
PRESTAZIONI SVOLTE<\/strong>: progetto esecutivo strutturale
INIZIO\/FINE LAVORI<\/strong>: 2003-2005<\/p>
La struttura nel suo complesso \u00e8 composta da una torre in conglomerato cementizio armato di sezione tubolare con diametro 2.50 m e con altezza totale 47 m. La torre \u00e8 collocata, con il suo spiccato, all'intemo delcapannone destinato a sede di trasmissione, pertanto fino a quota m. 5.0 circa viene celato alla vista.
La torre \u00e8 corredata con cinque livelli di terrazzamenti a quota in carpenteria metallica. Gli orizzontamenti sono muniti di montanti tubolari disposti radialmente verso l'esterno della torre stessa al fine di poter collocare su di essi le parabole di trasmissione. Le travi di impalcato di tali terrazzamenti disposte anch'esse radialmente rispetto al centro della torre. Dette travi sono vincolate a cerniera alla parete del fusto, con un tirante verticale in tubolare metallico collegato alla piattaforma in cemento armato che ha valenza statica di fare da vincolo di estremit\u00e0 indiretto per tutte le quattro piattaforme. Il collegamento tra il fusto e la soletta, con getto delle due componenti eseguito in fasi successive, \u00e8 costituito da manicotti e barre, entrambe filettate, per la giunzione delle armature senza sovrapposizione.
Particolare menzione merita lo studio del profilo del vento eseguito nel dominio delle frequenze; la determinazione del profilo del vento \u00e8 stata eseguita in accordo con le Normative vigenti in Italia, mentre l'analisi aerodinamica del vento sul fusto (studio dei coefficienti di forma) \u00e8 stata eseguita in accordo con EC1 e le pi\u00f9 recenti bibliografie in materia.
In questo modo si \u00e8 potuto tener conto, attraverso la determinazione il numero di Reynolds, della scabrosit\u00e0 della superficie investita dal vento, della snellezza della struttura (rapporto altezza - diametro) e della velocit\u00e0 del vento in ogni suo punto esaminato. Cos\u00ec facendo si arriva ad una determinazione del coefficiente di forma che meglio coglie il reale comportamento dell'opera nel suo insieme rispetto a quanto indicato nella Normativa italiana vigente.
\u00c8 stata inoltre eseguita l'analisi dinamica della struttura con la ricerca del primo modo di vibrare al fine di trovare il coefficiente dinamico Cd per la struttura. Tale ricerca \u00e8 stata condotta con l'ausilio degli scritti del Prof. Solari e permette di trovare il coefficiente moltiplicatore della spinta del vento dovuto al comportamento di raffica dello stesso. Tale valore di Cd viene introdotto numericamente come moltiplicatore del carico di vento di carattere statico. La fondazione della torre \u00e8 costituita da un plinto a pianta quadrata posto su pali trivellati. I pali raggiungono la profondit\u00e0 di m. 26.0, intestandosi nel livello ghiaioso presente da 23 m in poi,fino a tale quota attraversano strati limo-argillosi-sabbiosi che, anche per la presenza della falda, non garantiscono la portata richiesta ai pali. Ai pali eseguiti sono inoltre state effettuate prove non distruttive mediante cross-hole ultasonici al fine di controllare l'ottimale realizzazione dei pali sia nei confronti della profondit\u00e0 che della compattezza del getto stesso.
Infine, l'esecuzione di calcoli di dettaglio sulla stabilit\u00e0 del fronte di scavo nella esecuzione del plinto di fondazione hanno permesso di evitare la dispendiosa realizzazione di una paratia di contenimento scavo, richiesta in modo affrettato e senza giustificazione tecnica dalla Ditta esecutrice.<\/p>
