Abstract
In this research, to study mechanical behavior of a steel pier which four steel pipes are connected by shear hysteresis dampers made of low yielding steel, experiments and FE analyses were carried out. The experiments were conducted by four loading patterns which were monotonic torsional moment loading, cyclic loading under fixed axial force, and cyclic loading under fixed axial force and torsional moment. The experimental loading pattern models were also analyzed by finite element method. In addition, the parametric analyses were executed, which parameters were the amount of torsional moment, the loading direction and the width thickness ratio of the web panels. The results provided beneficial knowledge for design of the steel pier taking into the effects of account the torsional moment and shear plate buckling.
