The Dynamical Behaviour of Structures explores several developments made in the field of structural dynamics. The text provides innovative means to identify the effect of earthquakes on buildings of various types. The mathematical aspect of beam vibrations is discussed in detail, and the different types of vibrations are also explained.
The book gives a comprehensive discussion of the reactions of beams to moving loads; the vibrations of beam systems; and the beams on elastic foundations. The second part of the book focuses on the vibrations of plates and shells. In this section, an introduction is given to vibrations of rectangular and circular plates. The analysis of cylindrical and shallow shells then follows. The final chapter of the book discusses the structural vibrations that are influenced by its surrounding or underlying medium. The changes in these structures are then evaluated.
The text can provide invaluable insights for civil engineers, architects, students, and researchers in the field of mechanics.
