钢货架柱畸变屈曲的试验研究

给出受压钢货架柱性能的试验结果。对不同长度的钢货架柱进行试验研究,主要研究那些发生畸变屈曲的试件的性能。畸变屈曲一般发生在中等长度的试件上。即:长于那些发生局部屈曲强度的柱,但是也不能过长,以避免发生整体屈曲。测量了试件的变形量,而且,大部分构件发生的是一种畸变屈曲和整体屈曲组合的破坏模式。此外,已经证实尽管该破坏模式对试件强度的影响不大,但是如果考虑这个因素,目前设计程序的准确性将得到提高。

An Experimental Investigation of Distortional Buckling of Steel Storage Rack Columns

An experimental investigation on the behavior of steel storage rack columns subjected to compression is presented. Members of different lengths are tested, but special attention is focused on the behavior of the specimens having lengths that make them subject to distortional buckling. This mode of buckling can be observed in moderately long specimens;namely, longer than the stub columns used for the determination of the local buckling strength, but short enough to avoid the effects of global buckling. The d...
