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。結(jié)構(gòu)服役期間預(yù)加壓應(yīng)力可全部或部分抵消荷載導(dǎo)致的拉應(yīng)力，避免結(jié)構(gòu)破壞。買單根預(yù)應(yīng)力鋼絞線</p><p style="text-indent:25px">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。買單根預(yù)應(yīng)力鋼絞線</p><p style="text-indent:25px">二次效應(yīng)是體外預(yù)應(yīng)力結(jié)構(gòu)在彈性階段區(qū)別于體內(nèi)預(yù)應(yīng)力結(jié)構(gòu)的特征之一。由于二次效應(yīng)考慮的是體外預(yù)應(yīng)力鋼束與結(jié)構(gòu)豎向變形的差異，故這種效應(yīng)是非線性的，對二次效應(yīng)的研究必須考慮結(jié)構(gòu)的非線性影響。體外預(yù)應(yīng)力在有限元計算中的實現(xiàn) 體外預(yù)應(yīng)力的有限元計算主要有兩種方法： 1、以等效荷載的形式添加體外預(yù)應(yīng)力； 2、單獨建立體外束單元的方式實現(xiàn)。方法1能近似的計算預(yù)應(yīng)力損失，但無法考慮轉(zhuǎn)向塊的作用（粘結(jié)滑移），且由于方法1是以荷載形式表達(dá)的（沒有實際的結(jié)構(gòu)），所以難以考慮鋼束的二次效應(yīng)。方法2用結(jié)構(gòu)來模擬預(yù)應(yīng)力，因此能較好的考慮鋼束的二次效應(yīng)，但預(yù)應(yīng)力損失的計算與轉(zhuǎn)向塊的模擬存在一定的技術(shù)門檻，但是這并不是不能克服的，這一點在WISEPLUS中已經(jīng)提供了相關(guān)技術(shù)的實現(xiàn)。買單根預(yù)應(yīng)力鋼絞線</p></p><br
