Probabilistic Analysis of Botlek Bridge
The paper deals with probabilisticanalysis of the largest movable lift bridge of the world. The bridge system consists
of six reinforced concrete pylons and two steel decks 4000 tons weight eachconnected through ropes with counterweights. The
bridge system is in dynamic mode during movement of the decks and the counterweights, under the action of wind and
earthquakes. The real bridge structure has a high level of significance and accordingly not only deterministic calculations were
carried out but also stochastic analyses were required. The paper focuses the probabilistic analysis as the base of dynamic study
in design process of the bridge.The results had a high importance for practical application and design of the bridge.
