Study on Theoretical Elongation of Small Radius Prestressing Tendons in Anchorage Zone of Cable-stayed Bridge Pylon 斜拉桥索塔锚固区小半径预应力束理论伸长值研究
Study of Tensioning Elongation of Sharp Curvature Radius Tendons Beam Crystallizations 小曲率半径预应力束张拉延伸量研究
CONCLUSION: The tendon elongation zone is prolonged gradually under slow and continuous elongation, and its maximal broken load of the trial group was more than the one fourth of that of the normal tendons, which was enough to the daily life of the rabbits. 结论:肌腱切断后在缓慢牵伸应力作用下不断延长,形成的肌腱延长区的断裂载荷明显大于对照组,超过了正常肌腱最大断裂载荷的1/4,能够满足其日常生活的生理需要。
