鋼筋的機械性能有哪幾點決定?

添加時間:2019-06-05      發(fā)布人:http://www.zhuangpian.cn

  我們都曉得鋼筋機械性能需求經(jīng)過實驗來測定,丈量鋼筋質(zhì)量規(guī)范的機械性能有屈從點、抗拉強度、伸長率,冷彎性能等指標。接下來我們主要看一下這幾項都是什么規(guī)范。
  We all know that the mechanical properties of reinforcing bars are tested by experiments. The mechanical properties of reinforcing bars are measured by yield point, tensile strength, elongation and cold bending properties. Next let's look at the specifications.
  屈從點(fy):當鋼筋的應力超越屈從點以后,拉力不增加而變形卻顯著增加,將產(chǎn)生較大的剩余變形時,以這時的拉力值除以鋼筋的截面積所得到的鋼筋單位面積所承當?shù)睦χ担褪乔鼜狞cσs°
  Following point (fy): When the stress of steel bar exceeds the yield point, the tensile force does not increase, but the deformation increases significantly. When there will be a large residual deformation, the tensile force per unit area of steel bar obtained by dividing the tensile force value by the cross-sectional area of steel bar at this time is the yield point s degree.
  抗拉強度(fu):抗拉強度就是以鋼筋被拉斷前所能承當?shù)拇罄χ党凿摻罱孛娣e所得的拉力值,抗拉強度又稱為極限強度。它是應力一應變曲線中大的應力值,固然在強度計算中沒有直接意義,但卻是鋼筋機械性能中必不可少的保證項目。由于:
  Tensile strength (fu): Tensile strength is defined as the ultimate strength, which divides the maximum tensile force that the steel bar can bear before it is broken by the section area of the steel bar. It is the largest stress value in the stress-strain curve. Although it has no direct significance in strength calculation, it is an indispensable guarantee item in the mechanical properties of reinforcing bars. Because:

  (1)抗拉強度是鋼筋在接受靜力荷載的極限才能,能夠表示鋼筋在到達屈從點以后還有幾強度儲藏,是抵御塑性毀壞的重要指標。
  (1) Tensile strength is the ultimate ability of steel bars to accept static loads. It can indicate how much strength of steel bars is stored after reaching the yield point. It is an important index to resist plastic damage.
  (2)鋼筋有熔煉、軋制過程中的缺陷,以及鋼筋的化學成分含量的不穩(wěn)定,常常反映到抗拉強度上,當含碳量過高,軋制終止時溫渡過低,抗拉強度就可能很高;當含碳量少,鋼中非金屬夾雜物過多時,抗拉強度就較低。
  (2) Defects in steel bars during smelting and rolling, and the instability of chemical composition content of steel bars are often reflected in the tensile strength. When the carbon content is too high and the temperature at the end of rolling is too low, the tensile strength may be very high; when the carbon content is too low and there are too many non-metallic inclusions in steel, the tensile strength will be low.
