延性比 meaning in English
ductility ratio
Examples
- When the reinforcement is suitable , the yield state of member is similar , the ultimate state will change with the changes of p , fy and fc
但上述冈素对截面极限曲率的影响很人，即关系到构件截面的破坏形态（截面延性比的大小） 。 - 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。 - Here the hsc of sompa is achieved through adding super - effective water reducer , fined slag and silicon fume , and decreasing the water / cement ratio . by varying the area ( spacing ) of tension bars , compressive bars , vertical links and distribution steel and embedding steel fiber and polypropylene fiber we try to improve the behaviors of reinforced high performance concrete one - way spanning slabs in bending , so that its ductility be greater than 5 . with the same arrangement of steel the width of bending member is varied to observe the effect of the width / depth ratio on the ultimate compressive strain of concrete
通过变化受拉筋含筋率和受压筋、箍筋(钩筋、分布筋)含量，或掺加纤维使之成为钢纤维高强混凝土( sfrhsc )和聚丙烯纤维高强混凝土( pfrhsc ) ，对高强混凝土双筋截面梁、板的受弯性能进行了试验研究，试图改善高强混凝土受弯构件的延性，使其延性比大于5 ；并在相同配筋情况下，通过变化截面宽度，研究了高强混凝土受弯构件的宽高比对压区混凝土极限应变的影响；并对试验构件的裂缝发展情况进行了观测。 - The research shows that : 1 ) the ductility of the hsc bending members constructed is much greater than 5 ; 2 ) increasing the vertical links and distribution steel can increase the deflection under ultimate moment ; 3 ) with appropriate compressive bars , vertical links and distribution steel the increase of moment after yield and the decrease of moment under ultimate moment can be ignored , so the ductility of the hsc bending member is much larger ; 3 ) the width / depth ratio of hsc bending member has no obvious effect on the ultimate compressive strain of concrete ; 4 ) the method used here to calculate the deflection is applicable ; 5 ) the location of crack coincides with the location of vertical links and distribution steel ; 6 ) the bending property of the hsc structure under the blast load can meet the demand of protective engineering
研究表明：本文研究的梁、板构件的延性比远大于5 ；增加箍筋(钩筋、分布筋)含量，可以提高压区混凝土剥落时的挠度；在适当的受压筋、箍筋(钩筋、分布筋)含量下，可以忽略压区混凝土剥落瞬间的承载力下降，从而大大提高构件的延性；受弯构件的宽高比对压区混凝土极限应变的影响不明显；受弯构件的裂缝间距受箍筋(钩筋、分布筋)的布置影响；文中所用的承载力和变形计算方法是可行的。化爆试验表明，高强混凝土构件的动载抗弯性能能够满足防护结构的要求。
