Giorgio Diana (born 27 September 1936) is an Italian engineer, writer, and professor of Applied Mechanics at the Department of Mechanical Engineering of the Polytechnic University of Milan. [2] [3]
In 1961, Diana graduated in Mechanical Engineering at Polytechnic University of Milan, Italy. [2]
Diana designed aspects of the Strait of Messina Bridge related to aeroelastics and the bridge's proposed road-rail functionality. He has carried out Aerodynamic and aeroelastic analysis for the projects of the Stonecutters Bridge (Hong-Kong), Talavera (Spain), Adige (Italy). He carried out analyses of wind-induced vibrations and design of damping systems for some of the largest overhead power lines in the world, including the Orinoco Crossing (Venezuela), Lake Maracaibo Crossing (Venezuela), Gheshm Strait Crossing (Iran), Yangtze River Crossing (China). He has also carried out analyses of wind-induced vibrations on cables and design of damping systems for the British Airways London Eye (UK), Beijing Great Wheel (China), and Great Berlin Wheel (Germany) projects.
In sport, Diana worked on optimization of sail plans for the Oracle America's Cup team (USA), 2008–2009.
Diana has written several books, most often on the subject of the Messina Bridge. [4] [5]
During his career, Diana received the following awards. [3]
Messina is a harbour city and the capital of the Italian Metropolitan City of Messina. It is the third largest city on the island of Sicily, and the 13th largest city in Italy, with a population of more than 218,000 inhabitants in the city proper and about 650,000 in the Metropolitan City. It is located near the northeast corner of Sicily, at the Strait of Messina and it is an important access terminal to Calabria region, Villa San Giovanni, Reggio Calabria on the mainland. According to Eurostat the FUA of the metropolitan area of Messina has, in 2014, 277,584 inhabitants.
Aeroelasticity is the branch of physics and engineering studying the interactions between the inertial, elastic, and aerodynamic forces occurring while an elastic body is exposed to a fluid flow. The study of aeroelasticity may be broadly classified into two fields: static aeroelasticity dealing with the static or steady state response of an elastic body to a fluid flow, and dynamic aeroelasticity dealing with the body's dynamic response.
The Strait of Messina is a narrow strait between the eastern tip of Sicily and the western tip of Calabria in Southern Italy. It connects the Tyrrhenian Sea to the north with the Ionian Sea to the south, within the central Mediterranean. At its narrowest point, between Torre Faro and Villa San Giovanni, it is 3.1 km (1.9 mi) wide. At the city of Messina, it is 5.1 km (3.2 mi) wide. The strait's maximum depth is about 250 m (820 ft).
The 1940 Tacoma Narrows Bridge, the first bridge at this location, was a suspension bridge in the U.S. state of Washington that spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7 of the same year. The bridge's collapse has been described as "spectacular" and in subsequent decades "has attracted the attention of engineers, physicists, and mathematicians". Throughout its short existence, it was the world's third-longest suspension bridge by main span, behind the Golden Gate Bridge and the George Washington Bridge.
A tuned mass damper (TMD), also known as a harmonic absorber or seismic damper, is a device mounted in structures to reduce mechanical vibrations, consisting of a mass mounted on one or more damped springs. Its oscillation frequency is tuned to be similar to the resonant frequency of the object it is mounted to, and reduces the object's maximum amplitude while weighing much less than it.
The Polytechnic University of Turin is the oldest Italian public technical university. The university offers several courses in the fields of Engineering, Architecture, Urban Planning and Industrial Design, and is consistently ranked as one of the best universities in Italy and in the world. As of 2024, it is ranked 28th worldwide for Mechanical Engineering, 22nd for Petroleum Engineering, 21st for Architecture and is among the top 100 (52nd) engineering and technology universities in the world.
The Pylons of Messina are two free-standing steel towers, the Sicilian one in Torre Faro and the Calabrian one in Villa San Giovanni. They were used from 1955 to 1994 to carry a 220 kilovolt power line across the Strait of Messina, between the Scilla substation in Calabria on the Italian mainland at 38°14′42″N15°40′59″E and the Messina-Santo substation in Sicily at 38°15′57″N15°39′04″E.
An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy along large distances. It consists of one or more conductors suspended by towers or poles. Since the surrounding air provides good cooling, insulation along long passages, and allows optical inspection, overhead power lines are generally the lowest-cost method of power transmission for large quantities of electric energy.
The province of Reggio Calabria was a province in the Calabria region of Italy. It was the southernmost province in mainland Italy and is separated from the island of Sicily by the Strait of Messina. The capital was the city of Reggio.
The Strait of Messina Bridge is a planned 3.6-kilometre suspension bridge across the Strait of Messina, connecting Torre Faro in Sicily with Villa San Giovanni on the Italian peninsula.
The Polytechnic University of Milan is an Italian university located in Milan. It is the largest technical university in the country, with about 40,000 enrolled students. The university offers undergraduate, graduate, and higher education courses in engineering, architecture and design.
In fluid dynamics, vortex shedding is an oscillating flow that takes place when a fluid such as air or water flows past a bluff body at certain velocities, depending on the size and shape of the body. In this flow, vortices are created at the back of the body and detach periodically from either side of the body forming a Kármán vortex street. The fluid flow past the object creates alternating low-pressure vortices on the downstream side of the object. The object will tend to move toward the low-pressure zone.
A dashpot, also known as a damper, is a mechanical device that resists motion via viscous friction. The resulting force is proportional to the velocity, but acts in the opposite direction, slowing the motion and absorbing energy. It is commonly used in conjunction with a spring. The process and instrumentation diagram (P&ID) symbol for a dashpot is .
A Stockbridge damper is a tuned mass damper used to suppress wind-induced vibrations on slender structures such as overhead power lines, long cantilevered signs and cable-stayed bridges. The dumbbell-shaped device consists of two masses at the ends of a short length of cable or flexible rod, which is clamped at its middle to the main cable. The damper is designed to dissipate the energy of oscillations in the main cable to an acceptable level.
Reggina Calcio did renew its Serie A contract on the second consecutive occasion, ensuring the longest stay of the Calabrian club in the top division of Italian football. With returning coach Franco Colomba not being successful in his third stay at the club, Giancarlo Camolese guided the side to 13th place in the league. With only 29 goals scored, Reggina relied heavily on its defence for the survival, and Martin Jiránek plus defensive midfielder Davide Baiocco strengthened their reputations. After the season, Baiocco returned to Juventus, who in turn loaned him out to Reggina's arch-rivals Messina, newcomers for the 2004–05 season, setting up the first Messina strait derby in the highest division ever.
The Metropolitan Area of Strait of Messina, is the urban agglomeration around the Strait of Messina, and is one of the most populated and important areas of Southern Italy. It includes part of the Province of Messina, in Sicily, and part of the Province of Reggio Calabria, in Calabria.
The Palace of culture of Messina, inaugurated to the public as Palacultura Antonello da Messina, on 12 February 2010, is a multipurpose center located at No. 343 of Viale Boccetta in Messina.
The Stretto di Messina S.p.A. company was established in 1981 in implementation of law no. 1158/1971 of the Italian government to design, build and manage the Strait of Messina Bridge.
