切角端 meaning in Chinese

sniend

The analytical results shows that enlarging the longitudinal size of access hole effectively minimizes the potential of fracture at the groove welds between column and beam flange and the root of access hole
分析结果表明焊接孔长度的增大有效地降低了梁根部的对接焊缝和焊接孔切角端发生断裂的可能性，但过长的焊接孔长度将导致梁平面外稳定的丧失。
But over increasing the length of the access hole will give rise to the loss of lateral stability of beam . reducing the height of the access hole only does benefit to the standard connection in common use whose length of the access hole is shorter ; the potential for facture at the root of the access hole is minimized
对于常用的焊接孔长度较短的“标准型”节点，焊接孔高度的降低有利于减小节点在焊接孔切角端开裂的可能，而对于焊接孔长度增大的节点，焊接孔高度的降低则起到了相反的作用。
