Abstract
This paper presents the outline of damage to pipe piers caused by the Hyogoken-Nanbu Earthquake and the analysis of these piers under cyclic loading. rl'he local buckling and the peeling of paint were observed at the transitional point of the pipe thickness. The cyclic behavior of these piers is analyzed by the elasto-plastic finite element method. The analysis is done under 3 types of cyclic loading. According to the results of analysis, the buckling mode and the distribution of the yielded zone match the actual damage, and the most damaged pier is proved to have less seismic capacity.
