low-yield and high-ductile rod 低屈服高延性连杆
It is found that the ductile strengthen member (concrete fill steel tube) play an important role to prevent the structure from collapse after the shear walls partially yield.
结果表明，混凝土芯筒的剪力墙屈服后，其内置的延性加强构件(钢管柱)对结构的防倒塌有显著的作用。
Ductile Iron has a higher yield strength than cast steel 40k vs. 30k.
铸钢的屈服强度是30 K，而球墨铸铁的屈服强度更高，达到40 K。
Ductile iron has yield strength of 40k and cast iron has none.
球墨铸铁的屈服强度是40 K，而铸铁没有屈服强度。
