ultimate plain的意思|示意

From 0 load till about 0.8 times the ultimate load bearing capacity, the steel tube longitudinal strain distribution along the depth of cross-section obeys the plain section assumption.

从加载之初直到大约0.8倍的极限承载力，试件纵向应变沿截面高度的分布基本符合平截面假定。

The in-plain ultimate load carrying capacity of concrete filled steel tubular(CFST) laced columns compressed eccentrically is calculated based on design guidelines for CFST structure.
