| Abstract: | 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. |
