The Natural Frequencies of Multi-Storey Frames

Good approximations to engineering problems are, if anything, more important than lengthy rigorous solutions. This is particularly true in the dynamic analysis of structures since dynamic stability does not usually enter the design of a structure but will only be taken into consideration with regard to the safety of the established structure.
