| Abstract: | The snap-through buckling of two simple structures subjected to quasistatic loading is analyzed by use of the elastica theory of prismatic bars. In the first problem, the deformation of perfect and imperfect three-hinged deep trusses is considered and the results of the previous experimental observations are explained analytically. In the second problem, the snap-through behavior of a column restrained by an elastic wire is studied and a comparison of critical loads are made with the approximate solutions obtained recently by Nachbar 1]. |
