钢结构人行天桥曲箱梁中横隔板设置间距的有限元分析

ANALYSIS OF LATERAL DIAPHRAGM SPACE OF CURVED BOX BEAM FOR STEEL PASSENGER FOOT BRIDGE BY FEM

在曲箱梁中设置横隔板,可以改善箱梁受力性能,但设置过密横隔板会增加箱梁自重。因此确定横隔板设置间距至关重要。从横隔板设置间距对截面及腹板变形和应力分布的影响分析,确定横隔板的适当设置间距,供有关设计使用。

A lateral diaphragm in the curved box beam can improve the force property of the beam.The offect of the diaphragm space on the deformation and stress distribution of the section and web is analyzed,which can determine the proper space of the diaphragm,it may be a reference for designers.
