Vibrated Reinforced Concrete
or
vibrated ferro concrete
or
vibrated steel concrete.

la prima soluzione è la più usata secondo me.

Problems of reliability evaluation of reinforced concrete tower structures are discussed. Some methods for estimating reliability and durability (longevity) of such structures are proposed. Much attention is paid to solving problems of mechanical durability, longevity and reliability of the aerial power line supports made of vibrated reinforced concrete because these supports dominate in Lithuania. Parallel with these questions, aspects of longevity and reliability of centrifugal reinforced concrete masts are discussed.


The company was born in 1992 with the production of metal inserts for the pre-fabrication in vibrated reinforced concrete and pre-compressed reinforced concrete, as a supporting company of its sister-company Spav Prefabbricati;
