钢格栅板与钢梁焊接对钢梁稳定性的影响

随着钢格栅板作为平台板的广泛使用，经常会受到人的走动或者机械的振动等动荷栽作用，因此，对于动荷载较频繁的环境或者地震高发地区，钢格栅板一般采用焊接安装。在现有研究成果的基础上，运用有限元方法，对焊接钢格栅板的钢梁的稳定承载能力进行了系统的分析，得到一些有益的结论和新的见解。

STUDY ON THE EFFECT OF WELDED STEEL GRATING ON THE STEEL BEAM STABILITY

With its widespread use as a platform plate, steel bar grating is frequently impacted by dynamic-load such as walking and mechanical vibration. Therefore, for the frequent dynamic load situation and the high seismic area, welding is a common installation method for steel gating. On the basis of existing research results, using the finite element method, this paper conducted a systematic research on the bearing capacity and stability of the steel beam welded with steel bar grating. Some useful conclusions and new insights were obtained.
