Dunkerley's method is a mathematical approach used in structural engineering to estimate the natural frequency of vibration for frames and structures that are subjected to dynamic loads. This method is particularly useful for determining the fundamental frequency of vibration for buildings and other structures, which is essential for assessing their behavior under seismic and wind loads. The core idea behind Dunkerley's method is to find an approximate solution for the natural frequencies of multi-degree-of-freedom systems using the principles of virtual work and the Rayleigh quotient.
