Abstrait:

This paper describes the concept development and subsequent detailed design of the deep water tower foundations for the Izmit Bay suspension bridge with a main span of 1550m. The foundation concept developed is an innovative design combining a traditional cellular concrete caisson with two cylindrical steel/concrete composite columns. Because the foundation concept is particularly optimized for resisting severe seismic loads the paper focusses on the required advanced modelling of soil-structure-interaction in relation to non-linear seismic time history analyses. The marine environment and deep water represents important challenges in relation to construction and long-term durability. The paper describes innovative solutions to deal with these challenges.
