摘要: 针对宽箱梁受力表现出较强的空间效应的特点,建立精细化的空间有限元模型,以恒载(自重加二期恒载)作 用下的力学分布作为基础,对比研究了考虑顶板横向预应力作用时的宽箱梁受力特点,得到了一些有益的结论。

关键词: 宽箱梁, 横向预应力, 空间效应

Abstract: Considering the spatial effect of broad box girder subjected to engineering loads,a fine FEM model was established, which was used to study the mechanical distribution of broad box girder under transverse prestressing forces. This study was carried out on the basis of the mechanical distribution of broad box girder subjected to dead load. Finally,some valuable suggestions were proposed.

Key words: broad box girder, transverse prestressing force, spatial effect
