Abstract

Sensitivity analysis as an alternative approach can take structural parameters as variable and achieve the relationship only with one time analysis. The study on frequency sensitivity of a transmission tower is actively carried out in this study. The three dimensional analytical model of a transmission tower is established by using the finite element method. The sensitivity coefficients to natural frequencies are deduced based on the equation of motion of the tower. A real transmission tower constructed in China is taken as an example to examine the feasibility and reliability of the proposed sensitivity computation approach. The made observations demonstrate that the Young's modulus of the vertical major members plays an important role in the first two vibration modes in comparison with all the other vibration modes.
