Structural Integrity and Reliability Analysis

The Rion Antirion Bridge in Greece consists of a main bridge, 2252 m long and 27.20 m wide with two approaches one on each side of the Corinth Strait. The environment consists of deep water, deep soil strata consisting of weak alluvium and strong seismic activity. The bridge had to accommodate possible fault movements and the impact of a big tanker moving at a speed of 30 km/h. The bridge design consists of a cable-stayed bridge made of 3 central spans and 2 side spans with four pylons resting on concrete substructure foundations. The deck is a composite steel-concrete structure. The design phase of the project is outlined with reference to the foundations and soil reinforcement, analyses and behaviour of reinforced soil, dynamic analysis of the bridge, the behaviour of the structure, and the push-over analyses of pylons. The construction of the pylon bases, foundations and tension leg platform, upper part of the pylons, and deck are described. The bridge was completed in August 2004.
