某大跨PC连续梁桥零号块实体分析

On entity analysis of zero block on some large-span PC continuous beam bridge

以某大跨预应力混凝土连续梁桥为背景工程,考虑悬臂最不利状态下零号块受力,采用大型有限元程序M idasFEA进行分析,总结了预应力混凝土箱梁在复杂受力状态下的应力分布特点及建模方法。

Taking some large-span prestressed concrete continuous beam bridge as the background project, the paper considers the stress of the zero block under the most unfavorable status of the hanging arm, undertakes the analysis by adopting large finite elementary program, Midas FEA, and sums up the stress distribution features of the prestressed concrete box-girder in complex stress status.
