摘要：

The problem of dynamic response of fully clamped beams and flat arches under transverse impulsive loading is solved by Galerkin's method. Possibility of chaotic behavior of beams and arches is discussed; for this purpose displacement-time histories, phase portraits and power spectrum diagrams are put together.
