摘要
高墩大跨连续刚构桥在西部山区应用非常广泛,当桥梁位于近断层地区时,迫切需要解决桥梁抗震问题。以云南某高墩大跨连续刚构桥为工程背景,基于合理混凝土本构对比减震与非减震结构地震响应,提出了优化减震设计方案。
It is necessary to solve the special problems of seismic design of bridges in near-fault area,in spite of the wide application of high-pier and long-span continuous rigid frame bridges in mountain area. Taking the high-pier and long-span con- tinuous rigid frame bridge in Yunnan province as an engineering background,the structural optimization is provided,compa- ring the earthquake response of the seismic isolation design and the seismic design based on rational constitutive of concrete.
