Numerical simulation on damage to pipe piers in Hyogoken--Nanbu earthquake

摘要

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. The local buckling and the peeling of paint were observed at the transitional part of the pipe thickness. The cyclic behavior of these piers is analyzed by the elasto-plastic finite element method. The analyzed buckling mode and the distribution of the yielded zone match the actual damage.
