Abstract
The verification of existing steel structures especially steel bridges is in present one of the main problems of the structural engineers. The majority of existing railway steel bridges that have been built at the turn of the last century are riveted structures. Today many of these structures have already achieved a considerably age; therefore the establishment of the remaining fatigue safety of these structures is one of the most important tasks of contemporary society. Many of these bridges are still in operation after damages, several phases of repair and strengthening. The problem of these structures is the assessment of the present safety for modern traffic loads and the remaining service life. Along with the classical method of damage accumulation, a new approach based on the fracture mechanics principles is proposed. The paper presents the Romanian Methodology in this field with some case studies.
