可以分為(光面)鋼絞線、鍍鋅鋼絞線、涂環(huán)氧鋼絞線、鋁包鋼絞線、鍍銅鋼絞線、包塑鋼絞線等。制造過程分為單絲制造和絞線制造，制作單絲時采用(冷)拉絲技術，根據鋼絞線相關產品的不同材料可以是高碳鋼盤條、不銹鋼盤條或中低碳鋼盤條，如果需要鍍鋅，應在單絲上進行電鍍或熱鍍處理。絞線制造過程中采用絞線機將多根鋼絲絞合成產品，預應力鋼絞線還需要在成形后連續(xù)進行穩(wěn)定化處理，較終產品一般收在工字輪(reel)上或按無軸卷(reel-less)完工。好用的預應力鋼絞線截面預應力鋼絞線涂防腐油脂或石蠟后稱為無粘結預應力鋼絞線，預應力鋼絞線也有鍍鋅或鍍鋅鋁合金鋼絲制成的。</p><div

style="text-indent:25px">吊裝帶、橋梁用鋼絞線各自的優(yōu)勢：橋梁用的優(yōu)點在于耐磨、耐高溫、不易斷裂。橋梁用鋼絞線對環(huán)境的使用要求相對而言比較強，且適合用于大噸位的吊裝和高空吊裝。缺點在于在起吊稍重的箱裝設備時易損壞外包裝,主要就是在起吊時它的輕微磨擦就能損壞被吊物的表面。過粗的規(guī)格的不易伸展，不能用來起吊易燃易爆的罐體。吊裝帶有扁平吊裝帶和圓形吊裝帶，吊裝帶一般采用**力聚酯長絲制作，它的優(yōu)勢在于可以使用在易燃易爆環(huán)境下，而且分量輕、柔性好，易彎曲；吊裝帶有較高的抗拉強度，可以用顏色輕松辨別噸位；缺點在于當吊裝物有鋒利的邊時容易割傷，為保護吊裝帶免受割傷，可用一保護襯置于吊裝帶和被吊物之間。</p><p style="text-indent:25px">合格的鋼絞線的使用，不**能增強建筑的穩(wěn)定性能，還會給建筑的整體的耐久性加分不少。由于鋼絞線的種類很多，生產工藝的不同使得不同的鋼絞線又有他們各自的使用特點，所以在選擇鋼絞線時，選擇合理的適合的鋼絞線，對整個建筑施工，或者是其它工作中的使用十分重要。鋼絞線在生產過程中對產品的生成工藝和產品質量嚴格把關，根據需要，不同粗細的鋼絲絞合、不同數量的鋼絲絞合在一起，根據鋼絞線的應用領域經過不同的工藝生產出適合的鋼絞線。在工程結構構件承受外荷載之前,對受拉模塊中的鋼筋，施加預壓應力,增加構件的耐久性。</p><div

style="text-indent:25px">二次效應是體外預應力結構在彈性階段區(qū)別于體內預應力結構的特征之一。由于二次效應考慮的是體外預應力鋼束與結構豎向變形的差異，故這種效應是非線性的，對二次效應的研究必須考慮結構的非線性影響。體外預應力在有限元計算中的實現體外預應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應力； 2、單獨建立體外束單元的方式實現。方法1能近似的計算預應力損失，但無法考慮轉向塊的作用（粘結滑移），且由于方法1是以荷載形式表達的（沒有實際的結構），所以難以考慮鋼束的二次效應。方法2用結構來模擬預應力，因此能較好的考慮鋼束的二次效應，但預應力損失的計算與轉向塊的模擬存在一定的技術門檻，但是這并不是不能克服的，這一點在WISEPLUS中已經提供了相關技術的實現。質量好的預應力鋼絞線索頭重量</p><p
