Space trusses under certain conditions may be prone to snap- through buckling. The sudden reduction of the load carrying capacity of a single critical compression members, or a group of compression members, may lead to the snap-through buckling of the compression chord of the structure. This temporary loss of equilibrium due to snap-through normally results in a Dynamic force being applied to each node associated with the snap-through. In This paper a methodology based on energy methods is presented to determine The dynamic snap-through response of truss structures. Member failure is Taken into consideration by carefully following the buckling load-displacement Response of the member.
