specific optical rotation

Span ratio and crankle ratio are selected in this paper,which influence the applicability of plane-section assumption in the analysis of L-shaped RC columns.

本文选取剪跨比和弯扭比这两个影响平截面假定成立的主要参量,在截面层次上以截面应变误差分析作为平截面假定成立的定量判定依据,构件层次上以两种模型得出的柱顶侧向位移误差作为依据,对处于弹性阶段的L形柱平截面假定的适用性进行了探讨,得出了不同受力情况下平截面假定适用的最小剪跨比。

Taking into account the interrelation of bending and torsion in conditions of different torsion-bending ratio,the influencing factor of bending-torsion is adopted to calculate the bearing capacity of the concrete member subjec.

阐述了国内外弯扭受力构件的计算模式及弯扭的破坏机理,对变角度空间桁架模型所提出的受扭强度计算公式与国内外弯扭理论进行研究,在不同扭弯比情况下考虑弯扭相互影响,采用弯扭影响系数对弯、扭复合受力钢筋混凝土构件进行承载力计算。

Water was used as a working medium to investigate the internal heat transfer and flow resistance properties of the twisted tube with large twist ratio in the conditions of variable short-long diameter ratio(B/A=0.
