Abstract

A huge fire on Lazienkowski Bridge across Vistula River - one of the most important bridges in the center of Warsaw - capitol of Poland occurred on 14 of February 2015. The bridge was built in 1972-74as full steel structure with three wooden service decks between girders. It consisted of five four girders continuous spans 76,5+90,0+90,0+90,0+76,5 m. The fire started during the exchanging of these wooden elements under the first span. It started in the afternoon and was extinguished next day in the morning. During that time three spans were under fire. Extensive investigation and analysis were done during next 6 weeks including material investigation, geometrical verification of steel superstructure and FEM model analysis to determine the behavior of bridge during thermal overloads. Following results are presented in the paper i.e. local deformation of the deck and webs of the girders, global rotation of the outer girders and global displacement of the all four girders (also due to bearing and expansion joints behavior).
