摘要
体外索索力的测试在斜拉桥中得到了应用,但如何准确测量中小构件体外索的索力目前没有定论。本文通过理论推导给出了体外索索力和频率之间的实用计算公式,通过试验数据和有限元分析对实用计算公式进行了验证。结果表明:实用计算公式可以用来测试中小构件体外索的索力,误差满足实际工程的需要。
The test of external tendons＇ force in cablestayed has been applied, but how to measure accurately small and medium- sized component external tendons＇ force at present is not settled yet. This article gives practical calculation formulas between the force of external tendons and frequency through theoretical derivation, and verifies the practical calculation formulas through experimental data and finite element analysis. The results showed that the calculation formulas can be used to test the force of external tendons in small and medium -sized component, the error meet the actual needs of the project.
