The traditional machine-cut method ( or handwork cutting) is only the same with hot roll profiled bar, not the cold-firmed thin-wall steel.

传统的机械切条法（或手工割据）只适用于热轧型钢和钢板焊缝组合的构件中的残余应力测定，并不适用于冷弯薄壁型钢。

Damages first came out from some weak zones of H profiled bar joints such as weld seams and bolt joints, because rigid joints did not show enough tensibility under cyclic load.

试验过程中，刚性节点在循环荷载作用下没有表现足够的延性，H型钢连接件的焊缝及螺栓连接等薄弱区首先破坏；

The stress in primary support is very large especially in profiled bar steel frame, the inner and outside edge of steel frame are in stress condition and most steel frame stresses exceed steel yield limit, the steel stress in unstable condition;

初期支护受力很大，特别是钢架内、外缘均处于受压状态，而且钢架大部分均超过钢材的屈服极限，钢架处于失稳状态；

《 Judge picture of macrostructure defect for structural steel 》 GB/ T1979-2001 is the sole for profiled bar and flat bar in China, but the size of defect in the sample is not in proportion to the standard of the sample.

《结构钢低倍组织缺陷评级图》GB/T1979-2001是目前国内唯一钢铁型材、扁材低倍组织缺陷评级图，但样品缺陷的大、小与样品规格不成正比。
