延性特征 meaning in Chinese

ductility traits

Tow speciments of prestressed fabricated beam - column subassembly were tested under reversed cyclic loading . experimental studies were carried out to investigate the strain distribution , failure mechanism and load - bearing capacity on the beam - column connections , as well as ductility , hysteresis curves energy dissipation , displacement restoring capacity of full pc speciments
本文通过两榀预压装配式梁柱组合体在低周反复荷载下的试验，了解了预压装配式框架梁端截面应变分布、破坏机理和极限承载能力；探讨了全预应力配筋截面延性特征、滞回性能、耗能能力和变形恢复能力。
