Multi-level seismic finite element analysis and comparison on a four-span(75+135×2+75) m two-line continuous beam railway bridge were carried out to study the valuing method of the stiffness on the direction of horizontal static constraint of support.
以1座(75+135×2+75)m四跨连续梁双线铁路桥为例,对桥梁多级抗震有限元分析中支座水平静力约束方向上的弹簧刚度的取值问题进行了分析计算和对比研究,提出了改进的取值方法:多遇地震中,水平静力约束方向上的弹簧刚度可取为无穷大;在设计地震和罕遇地震时,水平静力约束方向上的弹簧刚度可按照水平静力自由方向上的弹簧刚度的取值方法进行取值。
