The earthquake simulation analysis of a pile supported steel-frame-building damaged due to the 1995 Hyogoken-Nanbu Earthquake is conducted by using the simple stick-beam on spring model to demonstrate the nonlinear behavior of the structure-pile-soil system. Subsequently, in order to investigate the seismic performance of piles, the elasto-plastic analysis due to applying incremental seismic loads statically is made by employing a frame model of the pile-soil system. Thus, the actual damage of piles, which is unclear because an on-the-spot investigation at the site is not conducted, is estimated from a combination of dynamic and static analyses. It is concluded that the pile foundation suffers only slight damage from the earthquake and represents a high performance against the seismic loads.
