WebAbstract. The paper is devoted to the dynamics of building structures excited by-sinusoidal excitation. The analysis indicates that the complicated response curves found for higher modes of some structures are a result of the interference of lower modes of vibration.

In Section 2.2 we move up a step and solve the analogous problem involving three masses. In Section 2.3 we solve the general problem involving N masses and show that the results reduce properly to the ones we already …

WebClamped Bar Modes. The frequency f 1 depends upon the density and elasticity of the material from which the bars are made. The amplitudes for the f 2 and f 3 modes would actually be much smaller than the fundamental. These mode frequencies appear with a tuning fork since it can be considered to be two clamped bars. Free bar modes.
