Normal modes of uniform beam
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. A … WebThe one end of the beam is fixed, and the other is simply supported. For the calculation, the elastic modulus E of the beam should be specified. As a result of calculations, the natural vibration frequency of the beam f is determined for the first vibration mode.
