initial tangent modulus 中文意思是什麼
initial tangent modulus
解釋
初始切線模量-
If asphalt concrete specimen is in stabilization by exert confining stress before the static triaxial test, it is then found that under the condition that time is long enough, the volume of the specimen will shorten gradually and stable around a fixed value, and the amount of compression is essentially the half of the volume of void itself. it is also found that in stabilization by exert confining stress the linear phrase will be shorten in the figure of the static triaxial test of specimen, while the initial tangent modulus will be augment. 3
在進行靜三軸試驗以前先對瀝青混凝土試件進行圍壓穩定，發現在時間足夠長的條件下，試件的體積會逐漸縮小，並逐漸穩定在某一定值，其壓縮量基本上為其本身孔隙體積的一半；經圍壓穩定后的試件靜三軸試驗曲線上的線性階段明顯縮短，而初始切線模量增大。 -
Theory analysis in this paper pointed out that the flexural - torsional buckling is the usual form of t - section steel. so the slenderness ratio of flexural - torsional buckling should be used when people give out the b / t ratio by the " equal stability " conception. initial stress, defects and tangent modulus are include in the deduce of the paper to get a rational b / t ratio
通過理論分析指出軸心受力剖分t型鋼整體失穩以彎扭屈曲為主，所以在運用「等穩定」方法確定腹板寬厚比限值時應與桿件的扭轉長細比「掛鉤」 ，並以此為出發點考慮殘余應力、初始缺陷，應用切線模量推導出了較為合理的腹板寬厚比限值公式。
