Long Span Buoyancy Bridge with Submerged Cable Anchoring

The purpose of this MSc thesis is to find a feasible concept for a circa 4500 m long buoyancy bridge, which is located at the Sognefjord in Norway. The concept should be structurally and aesthetically competitive. In contrast to bridges on shore with fixed supports, a buoyancy bridge is supported on floating pontoons. As result, loads will cause...

Analysis of force distribution on operating mechanisms in a bascule bridge

Bascule bridges can be designed with two operating mechanisms in order to open and close the bridge. Due to certain effects a difference in force per mechanism can occur. Therefore the Dutch standard for movable bridge, the VOBB, states to use a force distribution of 1/3 - 2/3 between the mechanisms. This means that both the mechanisms are...
