✦ Synopsis

The use of Dunkerley's first-order method for estimating the fundamental natural frequencies of tower structures is discussed. An asymmetric geometry may be considered, even though this leads to coupling between bending and torsion. The analysis of an asymmetric high-voltage transmission tower is considered as a practical example.
