load-bearing ultimate capacity 正截面极限承载力
The results show that the arch distortion weakens structural ultimate load bearing capacity, and increases lateral displacement at the bottom of .
分析表明，拱肋变形降低了结构的极限承载能力，并增大了其在正常使用状态下的侧向变形，以致拱脚外包混凝土开裂严重。
Ultimate load bearing capacity enhancement ratio increases as the longitudinal CFRP layers increase for members with the same steel tube outer diameter.
对于同一系列的试件，承载力提高率随着纵向CF RP层数的增大而增大。
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。
