| 摘 要： | 预先确定斜拉桥的弹塑性区域,把包含多微段平面变刚度梁单元推广应用于大跨度斜拉桥的非线性地震响应分析,用微段的刚度变化模拟钢筋混凝土的弹塑性性能,对双塔单索面钢筋混凝土斜拉桥进行了考虑几何非线性和材料非线性的地震响应分析,编制了相应的弹塑性分析程序,并与Huges单元分析结果进行了比较。结果表明:本文方法能较好地模拟在强震作用下钢筋混凝土斜拉桥的非线性性能,可以在大跨斜拉桥的非线性地震响应分析中应用。

| Abstract: | Imitated the elastic-plastic behavior of Reinforced Concrete with segmented varied rigidity beam element,the earthquake response of double-tower single face Reinforced Concrete cabled-stayed bridge is analyzed,where the material and geometric nonliearity are taken into account.The comparative results with Huges element indicate that the nonlinear behviors of Reinforced Concrete cable-stayed bridge under violent earthquake are accurately described via the proposed element. |
