Problems of lamella flanges in steel bridge construction
Original language description
As the plate elements of ordinary lamella flanges always exhibit unavoidable initial geometrical imperfections, a gap always occurs between them, into which the loaded lamella is pressed under load. Given the fact that the loading is many times repeated,the above phenomenon is also many times repeated, a pronounced cumulative damage process being thereby generated. This leads, as it became manifest during the authors´ tests, to the initiation and propagation of fatigue cracks in the longitudinal filletwelds connecting the individual lamellas, which can, of course, imperil the safety and useful lifetime of the bridge structure concerned.
