Abstract

Taking a single-tower steel cable-stayed bridge with a main span of 165 m as a research object, a refined calculation model of the steel tower was established. The historical seismic records adjusted by peak acceleration were selected as the ground motion input for the elasto plastic time-history analysis in the longitudinal direction of the bridge. The local instability of the steel plates and ultra-low cycle fatigue cracking characteristics of the steel tower were studied, and the applicability of the fiber model was discussed. Results show that the Pushover analysis method loaded along the height can predict the sequence and location of the seismic plastic development in the longitudinal direction of the steel tower. Although the fiber model can obtain the elastic-plastic seismic displacement response and the seismic damage location of the steel tower, it cannot accurately evaluate the residual deformation and the damage degree of the structure. The peak ground velocity (PGV)/peak ground acceleration (PGA) value of the input ground motion is an indicator that affects the degree of structural seismic damage. Under the same PGA, the seismic damage of the steel tower caused by ground motions with larger PGV/PGA values is significant. Therefore, the seismic performance verification of steel towers cable-stayed bridges should adopt the ground motion time history with larger PGV/PGA values.

Key words： steel tower seismic damage near-fault ground motions local instability of steel plate ultra-low cycle fatigue damage

斜拉桥钢塔地震损伤特性及输入地震动参数的影响

以主跨为165 m的独塔钢斜拉桥为研究对象，建立精细化钢塔计算模型. 选取经峰值加速度调整后的历史地震记录作为地震动输入，分析顺桥向弹塑性时程反应，研究钢塔的钢板局部失稳以及超低周疲劳开裂特性，讨论纤维模型的适用性. 结果表明，沿高度方向加载的Pushover法能够预测钢塔顺桥向地震塑性发展的顺序和位置；纤维模型能够获得钢塔的弹塑性地震位移反应以及地震损伤位置，不能精确评价结构残余变形与损伤程度；输入地震动的峰值地面速度（PGV）/峰值地面加速度（PGA）值是影响结构地震损伤程度的指标；当PGA相同时，PGV/PGA值越大的地震动引起的钢塔地震损伤越显著，钢塔斜拉桥抗震性能验算应选用PGV/PGA值大的地震动时程.
