Molybdenum alloys, such as TZM alloys are used as die materials, which are able to work at temperatures up to 1700� [3].
A more economical way is using nickel-base superalloy or Ni3Al-base alloys as die materials working in air, which was reported in Russia and Japan [4,5].

Introduction During the last decades cable-supported bridges (cable-stayed bridge and suspension bridge) have received much attention because of their ability to overcome long span, with reduced erection costs and improved materials utilization, and more and more cable-supported bridges are in-plan or under construction [1-3].
Consequently, from the deformational characteristics, the more stiffness pylons and reasonable cable parameters, such as the sag-span ratio, cross-section and materials, to reduce the girders’ deflection.
The stay cables’ anchor system and itsequivalent method For hp≤200m and the materials often used today, the curve form equation can be approximated by straight line.
