| Abstract: | On the assumption that the framed tower can be represented by multi-segment cantilever carrying a spring support,a mathematical expression to determine the natural frequencies of a framed tower is obtained by using the equation of the transverse vibration for the analytical model of elastic continuous body and the method of numerical solution.By comparison,calculated values are in good agreement with experimental values. |
