| Abstract: | The bending rigidity of prestressed pull rod is relatively small and its vibration frequency is similar to one of cord,so the determination of axial force of pull rod can be made by the principle of cord vibration. Taking the examination of prestressed pull rod under an arch in a natatorium as a sample,the working internal force of pull rod is determined by use of vibration method. |
