Abstract EN
Sensitivity analysis can take structural parameters as variable and achieve the relationship only with one time analysis, which will dramatically reduce the analytical work especially for large scale structures.
The comparative 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 (FE) method.
The sensitivity coefficients to natural frequencies are deduced based on the equation of motion of the tower.
In addition, the expression of the frequency sensitivity to Young’s modulus, density of material, the cross area of members, torsional stiffness, and bending moment inertia is proposed.
A real transmission tower constructed in China is taken as an example to examine the feasibility and reliability of the proposed sensitivity computation approach.
An intensive parametric study is conducted in detail in order to compare the sensitivity coefficients of different physical parameters.
The work on an example structure indicated that the magnitudes of the sensitivity coefficients of Young’s modulus, the density, and the cross area are much larger than those of the torsional stiffness and the bending moment inertia.
