ASPECTS OF DYNAMIC STABILITY OF STRUCTURES

The dynamic nature of the transient of a structure from stability to instability is emphasized. The need to consider flutter and the paradoxical effect of mass distribution and damping on flutter loads are pointed out. A criterion is formulated for deciding upon a structure to be of the divergence type. For structures of this type, a static approach to stability is permissible. Fortunately, the majority of structures in civil engineering are of the divergence type. However, this does not exempt the civil engineer from being prepared to investigate stability by means of dynamics whenever necessary. The importance of Liapunov's direct method for stability investigations has been stressed.
