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 co

A method for obtaining approximate fundamental frequencies of non-circular, doublyconnected membranes is developed. An approximate expression for the radius of each bounding curve is written as a truncated Fourier series. The deflection, which is written as a perturbation series of the modes of a ci
Seismic design codes generally specify empirical formulae to estimate the fundamental vibration periods of buildings. Currently, most building codes provide the same empirical formula to estimate the fundamental periods for steel plate shear walls and reinforced concrete shear walls. The work presen
