The ductility and ultimate strength of steel tubular piers with the inner cruciform plates, the stiffener plates, the concrete-filled sections and the outer tube subjected to monotonic and cyclic horizontaloading were studied analytically. Numerical analyses were carried out using the finite element package MARL. In order to deck the validity of the numerical analysis, the analytical results of stiffened steel tubular piers were compared with the previous experimental results. These effects of the radius -to-thickness ratio parameter and the slenderness ratio parameter on the ductility, the ultimate behavior and the accumulated energy absorption of these steel tubular piers were clarified.
