| 摘 要： | 连续刚构0#块处于墩梁固结处,该梁段构造复杂,内有大量的预应力束通过。为揭示其在各种不利工况下的空间应力分布情况,需建立相应的空间有限元模型进行分析。文章以一座连续刚构桥为工程背景,运用ANSYS有限元软件对0#块进行局部应力分析,结果表明0#块局部位置应力分布较复杂,应进行钢筋补强。

| Abstract: | In continuous rigid frame bridge,the 0 # blocks was located at consolidation of pier and girder with a lot of prestressing tendons. In order to reveal the spatial stress distribution in a variety of adverse conditions,a space finite model need to be established. Taking a continuous rigid frame bridge as an example,this paper analyzed local stress for the 0# block by using ANSYS finite element software. The results showed that distribution of local stress for the 0# block was complicated and the steel should be strengthened. |
