连续梁桥的零号块应力分析

Analysis on Stress of Zero Block of Continuous Girder Bridge

基于大型计算程序ANSYS,对连续梁桥的零号块建立了有限元模型。分别在不同的工况下对零号块进行了空间应力分析,揭示了连续梁上零号块的应力分布规律和受力特点,并为以后的设计提供了依据与合理化的建议。计算结果表明:按照现行的设计,零号块在各种最不利的荷载工况下应力状态良好。

The finite element model for zero block of continuous girder bridge is built based on ANSYS. Spatial stress of zero block under various working conditions is analyzed, and the distribution rule as well as force characteristics is revealed, which provides basis and reasonable advice for subsequent design. The result of calculation indicates that according to current design, the zero block is of favorable stress status even under the worst working condition.
