The tests show the importance of good concretecompaction for concrete-filled steel RHS stub columns.
试验充分证明了混凝土密实度对矩形钢管混凝土短柱的重要性。

There should be sufficient space between the resulting columns of bars to allow access for vibrators and good compaction of the concrete.
钢筋之间应该有足够的空间允许振捣器进入混凝土振捣和并使混泥土能良好的压实。
