| 中文摘要: |
| 通过借助于SAP2000有限元分析软件,对连续梁桥上设置的滑移支座(聚四氟乙烯支座),采用常用的3种非线性连接单元进行模拟:水平非线性弹簧单元、Wen塑性单元以及摩擦板单元.首先,简单介绍了3种单元的特性,然后以某地区四跨连续梁桥结构为例,对滑移支座分别采用以上3种连接单元进行非线性时程分析,对其分析结果进行对比,为今后桥梁支座的分析提供参考. |

| This paper analysing a software by the aid of SAP2000 finite element method,adopt 3 kinds nonlinearity link element in common use to carry out a simulation to the sliding bearings on continuous girder bridge(teflon bearing):Level nonlinearity spring element、Wen plasticity element and sliding board element.Firstly,the property of 3 kinds elements is introduced simply.Secondly,by taking a four-span continuous girder bridge in some area as an example,the sliding bearing adopts the above 3 kinds link element to carry out nonlinearity time history analysis respectively,contrast on it’s analytical result,the bridge bearing analysis provides a reference to the days to come. |
