| 摘 要： | 以宝汉高速涧口河六跨变截面大跨径连续刚构桥为例,借助于目前常用的Midas软件,对大跨径6跨变截面连续刚构桥的自振特性进行分析,了解此类结构的自振特点.通过动力时程分析法,对连续刚构桥进行纵向、横向、竖向的地震响应分析,以便在大跨度连续刚构桥设计及施工时,重点关注纵桥向的动力响应,由此对工程实践有一定借鉴作用.

| Abstract: | Taking six-span continuous rigid frame bridge for example which belong to BaoHan high spreed Jiankouhe,with the help of large-scale general-purpose finite element software Midas,we studied the vibration characteristics of its structure.By using dynamic time-history analysis of the full-bridge seismic response in three directions which in the longitudinal,crossrange and vertical,for rigid frame bridge design and construction,we could focus on the dynamic response of longitudinal bridge.That had a reference to engineering practice. |

| Keywords: | continuous rigid frame bridge dynamic properties analysis in time domain seismic response |
