FATIGUE STRENGTH OF WEATHERED AND DETERIORATED RIVETED MEMBERS

A study has been performed on the fatigue resistance of corroded and deteriorated riveted members. The need for this study arose from the concern with the large number of riveted structures functioning today that have various degrees of corrosion and potential fatigue damage. The validity of AASHTO and American Railway Engineering Association category D that is generally used for riveted connections is uncertain, particularly near the fatigue limit. A series of fatigue tests was carried out on 80-year-old steel bridge stringers with a riveted built-up cross section. The stringers were significantly corroded along the compression flange and locally at the tension flange. The stress ranges that were applied were selected between the fatigue limits of design categories C and D. The corroded region of the tension flange proved to be the most severe condition, varying between categories C and E. The category D fatigue limit appears to be applicable to the rivet detail studied. The reduction of the compression flanges had no effect on the performance of the member. A strong frictional bond between section components was found to have a beneficial effect on fatigue life. A series of reduced-temperature tests on a cracked stringer did not induce fracture of the cracked component and confirmed the redundancy of riveted built-up sections fabricated from mild steel.
