摘要
介绍了频率法测试斜拉索索力的原理,并对斜拉索索力识别提出了一种改进方法。通过现场实际测试,证明采用该法较其他常用方法而言,固有频率识别精度得到了很大提高,从而显著地提高了频率法索力识别精度。
This paper introduced the principle of stay cable tension test with frequency method, and put forward a improved method to tension identification. It is proved that using this method can more enhance the identification accuracy of ftmdamental frequency than other methods by practical on-site test, so it can significantly enhance the identification accuracy o fcable tension.
