battened column meaning in Chinese

双肢柱

The member bearing compression in the truss could be regard as a battened column with the single axis of symmetry
这种角钢桁架中的受压件在结构上是一个单轴对称缀板柱。
Moreover , with the datum come from calculation and test , it seams that after the number of batten floor n > 3 the change of b effected by n is too weak to be ignored . hence , that indicates it is available that the laterlly buckle of the batten column with the single axis of symmetry could be calculated with b worked out from h - shaped anglicizing element without n
此外，由电算和实验分析可见，值在缀板层数n 3以后，其变化受n值的影响不大，这说明用h计算单元导出的与缀板层数无关的值计算公式是可以用于单轴对称缀板柱的侧向屈的计算。
