slenderness ratio

The influence factors on the effective length factor such as the base plate thickness, the slenderness ratio, column section size and elastic modulus of concrete were studied based on the calculation of effective length factor of the specimen.

在对试验试件柱计算长度系数进行计算的基础上分析了底板厚度、柱截面尺寸、长细比以及混凝土弹性模量对计算长度系数的影响。

The results show that the plastic extension would not occur in tensile region until eccentricity is large and slenderness ratio is small.

研究结果表明：除相对偏心率很大及长细比很小的情况外，工字形截面偏心压杆受拉翼缘不会进入塑性状态；

The resista nce decreases intensely when the slenderness ratio of the hot molding sand layer increases.

阻力随干砂层长细比的增加而急剧减小.

μ m, the slenderness ratio of less than 2 ∶ 1, the single particle of water and gypsum ratio is 0.22 and 3-days compression strength reached 61.1? MPa of alpha hemihydrated gypsum.

制备了二轴平均径12.5μm、长径比2∶1、单一粒径水膏比0.223、d抗压强度达到61.1MPa的α半水石膏。

It was found that, in general, ascending time ratio, fire load ratio, cross-section dimension and slenderness ratio have a significant influence on residual strength.

得出结论：升温时间比、火灾荷载比、截面边长以及长细比是影响火灾全过程作用后圆钢管混凝土柱剩余承载力的主要影响参数。
