| Abstract: | In this paper a building of the multistory rigid frames is separated into a series of free motion bodies.According to D'alembert's principle the system of the motion equations is derived.The normal modes of vibrations, the eigenvalues,the normalization modal shapes and the modal matrix are described briefly with some practical examples for use. |
