style="text-indent:25px">在多數(shù)后張預(yù)應(yīng)力及先張預(yù)應(yīng)力工程中，光面鋼絞線是較普遍采用的預(yù)應(yīng)力鋼材。模拔鋼絞線主要用于提升工程，也用于核電之類的工程。鍍鋅鋼絞線常用于橋梁的系桿、拉索及體外預(yù)應(yīng)力工程。涂環(huán)氧樹脂的鋼絞線用途和鍍鋅預(yù)應(yīng)力鋼絞線類似。各國都有針對(duì)預(yù)應(yīng)力鋼絞線的標(biāo)準(zhǔn)，如:中國標(biāo)準(zhǔn)GB/T 5224、美標(biāo)ASTM A416、英標(biāo)BS 5896及日標(biāo)JIS G3536、澳新標(biāo)AS/NZS 4672、巴西標(biāo)準(zhǔn)NBR-7483。預(yù)應(yīng)力鋼絞線的主要特點(diǎn)是強(qiáng)度高和松弛性能好，另外展開時(shí)較挺直。常見抗拉強(qiáng)度等級(jí)為1860兆帕，還有1720、1770、1960、2000、2100兆帕之類的強(qiáng)度等級(jí)。這種鋼材的屈服強(qiáng)度也很高。預(yù)應(yīng)力鋼絞線經(jīng)消除應(yīng)力處理(穩(wěn)定化處理)。</p><div
