As a new variety of steel wire in our country, the mid - strength ( 1270mpa ) spiral - ribs steel wire has many excellences such as high strength, good ductility, credible felting and anchoring capability witn concrete and so on. the pre - stressed concrete slab with this sort of steel wire has good mechanical property. so it is an ideal substitute to the cold - processed wires traditionally adopted in pre - stressed concrete slabs

Because of the former anchorage systems designed according to matching 1860mpa strength strands in the beginning of 90 ", they can not be suitable any more for the super strength strands with 2000mpa. therefore, some accidents occurred such as strands sliding and broken when tensioning. in addition, the advantages of the new materials as their high mechanics performance are not be used completely as the prestressing structures was designed as per the 1860mpa strands, which will result in the waste of materials, in view of the above - mentioned facts, by means of analyzing the development of anchorage systems home and abroad, in connection with the characteristics of the super strength strands ( 2000mpa ), this topic made a research on hvm15 anchorages by theoretical calculation and finite element analysis, and also on the manufacturing process and test
隨著預應力技術的發展和冶金工業冶煉技術的不斷進步,預應力鋼絞線的強度不斷提高,由原來1470mpa提高到1860mpa , 90年代末期已出現了2000mpa超高強鋼絞線,而原來的是在90年代初期按抗拉強度為1860mpa的鋼絞線標準設計的,因此,原有的
