The Ciminiera del Tannino is a double pipe brickwork chimney, tall about 45 m and based on a cilindrical base tall 2.25 m (also this made of brickwork).

Abstract
The Ciminiera del Tannino is a double pipe brickwork chimney, tall about 45 m and based on a cilindrical base tall 2.25 m (also this made of brickwork). The outer tube has a base diameter of 3.5 m and, at the crown, of 1.5 m. The outer tube thickness is 26 cm and the inner tube thickness is 15 cm; the inner tube has a constant diameter of 1.7 m and at 38 m height disappeared penetrating the outer one. The chimney was built in the early twentieth century and has the same symptoms of degradation as the other brickwork chimneys built in Italy in the same years. The symptoms are due to the weather and the frost cycles that are no longer counteracted by the time of disuse, including the mortar washout, exfoliation of the bricks and the deviation from the vertical. We have made linear tests in static and dynamic field and, after describing the survey campaign, the results of the analysis are discussed.File | Dimensione | Formato | |
