【摘要】 针对在强震作用下钢筋混凝土柱式桥墩会进入塑性状态的特性,采用有刚度退化的武田三线型滞回模型(弯矩—曲率关系),编制了非线性时程有限元程序,对一典型的双柱式桥墩进行了弹塑性抗震分析,得出了一些有益的结论。更多还原

【Abstract】 To counter the characteristics of that reinforced concrete column type piers can enter into plastic state under the action of strong seism, it is used to Wutian three linear hysteretic model with rigidity deterioration (relation of moment-curvature) and it compiles non-linear course element finite program to make elastic and plastic anti-seismic analysis for a typical double-column type piers. So it draws some beneficial conclusions.更多还原
