ABSTRACT
ABSTRACT: This paper shows several examples of such cracks. An attempt is made to explain their nature and genesis. Also several ways of repairing effectively this kind of dangerous damage to bridge structures are demonstrated. A description of the weld cracks, discovered during expertise and field test work, in structural components of the wind bracings in a steel three-span railroad bridge with simply-supported spans and an open deck situated on the Wroclaw – Poznan railroad line is presented.
