介绍了日本兵库县南部地震对钢管桥墩造成损坏的大致情况及循环荷载条件下 ,受损桥墩的分析结果。桥墩的周期特性采用弹 -塑性有限元法分析。分析得到的屈曲形态和屈服区域的分布与真实破坏情况吻合
The general situation of damage to the steel tube piers caused by the southern earthquake in Hyogo Prefecture, Japan, and the analysis results of damaged piers under cyclic loading conditions are introduced. The periodic characteristics of piers are analyzed by elastic-plastic FEM. The analysis of the buckling morphology and the distribution of yield zone are consistent with the actual damage
