| Abstract: | In the measurement of cable force of suspenders of arch bridge,the method for measurement of frequency response function can be used to determine the natural frequency of short cable suspenders and in accordance with the actual boundary conditions and types of vibration modes,to determine the rational calculation length for cable force of the suspenders and to accurately measure and obtain the tensile force of the suspenders.The accuracy of the method as mentioned can satisfy the requirements for construction in the technical specifications. |
| Keywords: | arch bridge suspender cable force frequency response function natural frequency measurement technique |
