Abstract
This paper has shown the results of numerical experiments based on software systems and aimed at the evaluation of orthotropic deck fatigue durability of motor road bridges.
Motor road bridges with steel orthotropic deck are widely used in our country and abroad. Moreover, the orthotropic deck is the main bearing element of the bridge floor. The structural feature of the orthotropic deck is the use of thin-walled elements of longitudinal and transverse ribs secured with the deck plate by welding.
Best practices in operating of motor road bridges with orthotropic deck show that within the initial period of 10– 20 years some fatigue cracks appear in the elements of orthotropic deck namely in in the longitudinal and transverse ribs, and sometimes in deck plate. For this reason, the problem of ensuring the fatigue durability in the superstructure elements of the motor road bridges and the evaluation of their resources is highly relevant.
The paper presents the results of numerical experiments performed for the steel orthotropic bridge deck over the Irtysh River at the motor road of Omsk Southern bypass (R-254), commissioned in 1995. Calculations are carried out by the finite element method. The specific locations of potential fatigue-related damages have been shown.
