Long-span bridges are special structures that require
advanced analysis techniques to examine their performance. This paper presents
a procedure developed to model the Confederation Bridge using 3-D beam elements.
The model was validated using the data collected before the opening of the
bridge to the public. The bridge was instrumented to conduct
fullscale static and dynamic tests. The static tests were to measure the
deflection of the bridge pier while the dynamic tests to
measure the free vibrations of the pier due to a sudden release of the static
load. Confederation Bridge is one of the longest reinforced concrete bridges in
the world. It connects the province of Prince Edward Island and the province of
New Brunswick in Canada. Due to its strategic location and vital role as a
transportation link between these two provinces, it was designed using higher
safety factors than those for typical highway bridges. After validating
the present numerical model, a procedure was developed to evaluate the
performance of similar bridges subjected to traffic and seismic loads. It is of
interest to note that the foundation stiffness and the modulus of elasticity of
the concrete have significant effects on the structural responses of the
