Abstract

<p>The load-carrying capacity of two old steel portal frame bridges, built in 1907 and 1912 has been determined, using FE-models and taking into account the damage due to corrosion, found during inspection. For this, adequate real traffic models have been used. The capacity of both bridges proved to be insufficient, mainly due to corrosion of the outside portals. The frame cross-sections are asymmetrical, since reduction of the area is considered for tension and not for compressed parts. Two alternatives are considered for refurbishment. Replacing corroded plates and profiles on site being impossible, the alternative to reduce dead weight seems more feasible.</p>
