摘要
体外预应力加固结构的钢索振动是其疲劳破坏和脱锚的诱因之一,基于拉索振动理论,对体外索的固有振动进行分析,研究和验证体外索的自由长度,研究成果可有效指导体外预应力加固工程实践。
Fatigue and anchor failure of steel cable are often caused by the cable vibration in these externally prestressed reinforcement structures.Based on the vibration theory of cable,this paper analyzes and verifies the inherent vibration and free length of steel cable.Results from this study may efficiently instruct the externally prestressed reinforcement engineering practice.
