摘要
以北京市昌平区温榆河景观桥为背景,对V形墩的选型和分析步骤进行阐述。采用有限元软件MIDAS-FEA建立V形墩的有限元实体模型,通过对V形墩进行局部应力分析,掌握其受力特性和关键部位的应力状态,为同类工程的方案选型及结构优化提供参考意见。
Taking a landscape bridge on Wenyu River in Changping District of Beijing, the article sets forth the selection and analysis step of V- shaped pier. The finite element solid model of V- shaped pier is established by the finite element software MIDAS- FEA. According to the local stress analysis of V- shaped pier, its stress characteristic and the stress status of key positions are mastered to provide the reference for the scheme selection and the structure optimization of the similar projects.
