Abstract
The paper presents the new bridge over the river Acheloos in Greece. The position of the bridge poses several construction and design challenges, mostly due to the soil characteristics at the foundation, the increased seismicity of the region and the high flow of the river. The project involves the construction of a small balanced cantilever bridge with three spans of length 47.5m – 80m – 47.5m. The main innovation in the structure is that the deck is supported exclusively on high damping rubber bearings, a technique not commonly encountered in such bridges. The selection of this structural system was a result of the poor geotechnical / foundation conditions, which differed considerably among the piers, as well as their low height. This led to the design of special deck stabilizing systems for the various construction stages. The design included application of the principles of earthquake engineering, an advanced construction schedule and a displacement monitoring procedure. Information regarding various analysis and design aspects, construction details as well as cost data are also presented.
