1. Introduction
This paper presents the study of the damage causes occurring in one of prestressed steel cables of a suspension bridge. The bridge is used to cross one of the most important rivers in the centre of Portugal. The main structural elements of the bridge are steel cables. Each cable is composed of 84 wires, distributed by 12 (6 + 1) twisted wires. Each of the wires has a thickness between 4.5 mm and 4.65 mm. All the damaged cable part, subject of this study (Fig. 1) matched inside the anchor, with a length of 1950 mm. The damage in the wires caused the collapse of the bridge. As a result there was a significant disturbance in traffic over the bridge because it stopped for a significant period of time and were made repair operations (NOE, 2004). In some wires occurred failures due to excessive oxidation, corrosion. Therefore, was performed a study to assess the damage process. The cables presented distinct fractures modes, identified macroscopically: 21 wires, corresponding to all three rods winding, exhibited ductile fracture surfaces, type ‘‘cup and cone’’ (Fig. 2), near the beginning of the anchor (between 100 and 250 mm).
