强震作用下球面网壳动力强度破坏研究
2.
With a finite element software ANSYS, the dynamic response of reticular shells under severe earthquake excitation was investigated, in which geometric non-linearity and material non-linearity were all taken into account.
借助Ansys有限元软件,对一单层双曲抛物面网壳在地震作用下的动力稳定性进行了研究,在考虑结构的几何非线性和材料非线性的前提下,对在强震下结构关键节点位移随地震加速度峰值的变化情况进行了跟踪,获得了对其塑性发展情况的认识,同时分析了不同地震波对结构动力稳定性的影响。
3.
At tresent,there is no seismic design code for long span and high pier continuing girder bridges,especially under severe earthquake.
以国外某大桥为例,建立了全桥的动力分析模型,计算了结构的动力特性和地震响应,针对大桥在强震作用下主梁位移反应过大以及对支座抗剪要求过高的特点,讨论了采用粘滞阻尼器和双曲面球型减隔震支座的减隔震效果,研究结果表明这些措施是有效的,可为同类大跨高墩连续梁桥的抗震设计提供参考。
