| 摘 要： | 运用渡槽薄壁结构弹塑性动力分析模型,开展了渡槽非线性地震响应分析计算。该渡槽薄壁结构弹塑性动力分析模型集渡槽薄壁结构线弹性模型和非线性多弹簧模型为一体,应用多弹簧等效关系模拟结构塑性铰区的非线性滞回特性。经结构线弹性和非线性地震响应比较,结果表明两者存在差异,开展大型渡槽结构非线性地震响应分析是很有必要的。

| Abstract: | Based on the elastic-plastic dynamic model of the thin-wall structure aqueduct,the non-linear earthquake response analysis is presented.The aqueduct elastic-plastic dynamic model is combined with the aqueduct thin-wall elastic model and non-linear multi-spring model.The non-linear hysteretic characteristic of the plastic hinge is simulated by use of the multi-spring equivalent relationship,and the influences of the section biaxial moment and the axial deformation are all taken into consideration.The calculated results show that the elastic value and the plastic value for the agueduct are different.It is necessary to calculate the aqueduct non-linear earthquake response. |
