style="text-indent:25px">體外預(yù)應(yīng)力鋼筋與混凝土截面變形不協(xié)調(diào)，在應(yīng)力計算中不能將體外預(yù)應(yīng)力鋼束面積計入換算截面的特征。由于管道在結(jié)構(gòu)體外，直線段體外預(yù)應(yīng)力鋼束的摩阻損失小，幾乎可以忽略不計，而曲線段體外預(yù)應(yīng)力鋼束的摩擦系數(shù)與采用的體外預(yù)應(yīng)力鋼束類型有關(guān)。由于截面變形造成的預(yù)應(yīng)力損失需根據(jù)體外預(yù)應(yīng)力體系與結(jié)構(gòu)的粘結(jié)關(guān)系來計算。這部分包括混凝土彈性壓縮損失和混凝土徐變、收縮引起的預(yù)應(yīng)力損失，定購回收預(yù)應(yīng)力鋼絞線。若體外預(yù)應(yīng)力鋼束為無粘結(jié)形式，定購回收預(yù)應(yīng)力鋼絞線，定購回收預(yù)應(yīng)力鋼絞線，則這部分損失計算與錨固點間相對位移差有關(guān)。故其計算方法與體內(nèi)預(yù)應(yīng)力鋼束不同。預(yù)應(yīng)力鋼絞線按鋼絞線結(jié)構(gòu)將一定數(shù)量的鋼絲絞合成股，再經(jīng)過消除應(yīng)力的穩(wěn)定化處理過程而成。定購回收預(yù)應(yīng)力鋼絞線</p><div

style="text-indent:25px">什么是預(yù)應(yīng)力鋼絞線?它的作用是什么?它的放置原則是什么?首先回答什么是預(yù)應(yīng)力鋼絞線。所謂的預(yù)應(yīng)力鋼筋簡單地理解為鋼絲。它的拉伸極限很高。在箱梁內(nèi)放置預(yù)應(yīng)力束，將預(yù)應(yīng)力束拉出并固定束的兩端，在梁嵌入階段對混凝土施加壓力。眾所周知，混凝土的抗拉強度很低，但其抗壓能力很強。因此，在混凝土的拉伸區(qū)域，通常采用預(yù)應(yīng)力鋼絞線來抵消某些外部荷載的張力。我們來談?wù)勏淞骸τ谄胀ㄆ胀ㄏ淞?，其?yīng)力模式為底拉、頂壓和腹板抗剪。因此，通?？梢钥吹筋A(yù)應(yīng)力鋼絞線鋪設(shè)在簡易箱梁的底部和腹板上，而屋面混凝土則受到抵抗。沒有發(fā)絲的頂端的力量應(yīng)該足夠。膜結(jié)構(gòu)中預(yù)應(yīng)力是一個十分復(fù)雜的因素，主要與膜材、建筑形式、安裝方法等有關(guān)。怎么能找到豎向預(yù)應(yīng)力鋼絞線</p><p
