The basic premise of seismic design allows structures to deform inelastically in large earthquakes as long as the deformation capacity of the structure is sufficiently large when compared to the deformation demands imposed by earthquake excitation. In the case of steel bridge structures, such provisions for ductility are difficult to achieve, especially when using welded connection between bridge columns and cap beams. In this seminar, a new connection design has been proposed which aims to address the shortcomings of traditional welded connections in steel bridges. Through the use of large scale testing, finite element analysis, and shake table testing, the connection has been shown to significantly improve the performance of steel bridges. Furthermore, the connection is rather simple to construct while also cost efficient.
