ductility ratio meaning in English
延性比
Examples
- The ductility ratio is a index of measuring the ductility of material , section and member . the ratio is bigger as the ductility is better
延性比是度量材料、截面或构件延性的一种指标，延性比越大说明材料、截面或构件的延性越好，反之，延性越差。 - By taking axial compression ratio , local angle , stirrup space , the ratio of stirrup and etc . into consideration , the author studies the displacement ductility ratio for speical - shaped columns such as l shape , t shape and t shape
摘要通过考虑不同轴压比、不同加载角度和不同配筋率等情况，对异形柱位移延性比进行了研究。 - When the axial compression ratio increases more than 0 . 42 , the variation of the displacement ductility ratios is small ; when the stirrup ratio per unit volume increases more than 1 . 9 % , the displacement ductility increases slowly ; with increasing the shear span ratio a , the displacement ductility increases for , < 1 . 5 , decreases for > 1 . 5
当轴压力系数增加到0 . 42以后，位移延性的变化较小；体积配箍率增加到1 . 9 %后，位移延性的增长减缓；当剪跨比小于1 . 5时，型钢混凝土柱的延性系数随剪跨比的增加而提高；但当剪跨比大于1 . 5时，随着剪跨比的增加，型钢混凝土柱位移延性系数有所降低。 - Details behavior as bellows : ( 1 ) the damping force of the damper with concrete ductility column is higher , and the final damping force smoothly decreases . ( 2 ) the ductility ratio of the damper with concrete ductility column is larger , so it has good ductility and its most level displacement is 1 / 14 ~ 1 / 8 of the column height . ( 3 ) the hysteretic curve of the damper with concrete ductility column is plumper
具体性能如下: ( 1 )混凝土延性柱耗能器的阻尼力比较高,后期阻尼力下降比较平缓; ( 2 )混凝土延性柱耗能器的位移延性系数较大,具有较好的延性,最大水平位移达到柱高的1 / 14 1 / 8 ; ( 3 )混凝土延性柱耗能器的滞回曲线饱满; ( 4 )混凝土延性柱耗能器中延性柱屈服后等效粘滞阻尼系数迅速增大,消耗地震能量的能力增大; ( 5 )混凝土延性柱耗能器中每根延性柱的破坏形态基本一致,表现了良好的共同工作性能。 - In this paper , the ductility of steel bar is expressed by ductility ratio b , the figure of dividing ultimate strain by yield strain . the ductility of section is expressed by ductility of section ratio , the figure of dividing ultimate curvature by yield curvature . the displacement ductility is expressed by displacement ductility ratio , the figure of dividing ultimate displacement by yield displacement
论文中钢筋延性采用钢筋延性比b来表示，即极限应变与屈服应变的比值；构件截面延性采用截面延性比来表示，即极限曲率与屈服曲率的比值；构件位移延性采用位移延性比_来表示，即极限位移与屈服位移的比值。
