Stay Cables Anchor Head Design and Strength Analysis

Xu GAO, Zhi-wen XIE


Based on mathematical statistics and theory of reliability, combining with engineering practice, simple and practical stay cables anchor head intensity and the calculating formula of anchorage length are deduced. These formulas are proven by actual engineering and have a guiding significance for small and medium sized cable-stayed structure project. The anchor head is an important structure in cable structure, under tension forces of cables or gravity. The requirement of the anchor head is: reliable operation, simple manufacturing process, easy replacement, low cost, life long, good corrosion resistance and hot melt. Cable bending will make its tensile strength is reduced, so the unfavorable use fixture to be fixed. Usually use hot melt technology manufacturing anchor head, and then to anchorage.
