ANALYSIS OF THE BEHAVIOUR OF PRESTRESSED BEAMS AFFECTED BY FROST

ANALISIS DEL COMPORTAMIENTO DE UNAS VIGAS PRETENSADAS AFECTADAS POR LA HELADA.

One of the cases of post-tensioned structures damaged by ice formed in ungrouted ducts, during the winter of 1970-71 in Spain, is discussed. The case concerns prestressed beams for the construction of two viaducts of the Molins de Rey-Martorell section of the Barcelona-Tarragona Motorway. Certain aspects are analysed, such as the characteristics of the beams, protection envisaged, climatic data, damage to the beams, decisions taken, object of the test envisaged and the associated difficulties. The test carried out, the results obtained and the protection applied to the reinforcement after verification of the behaviour of the test beam are mentioned. /TRRL/
