N2 - 4-legged bridge steel truss piers provide support for gravity, transverse, and longitudinal lateral loads of bridges. Allowing a controlled rocking response for seismic resistance of 4-legged truss piers requires the development of design equations considering ground motions in two horizontal directions and vertical excitation. First, the static kinematic and hysteretic bi-directional behavior of controlled rocking 4-legged piers, relevant for design, is developed analytically and some of the design rules are established. The seismic response of a 4-legged pier to 3 components of ground excitation is then investigated using inelastic, dynamic time history analyses.
