FURTHER STUDIES OF CREEP BUCKLING OF CURVED BEAM UNDER LATERAL LOADING

摘要

The creep buckling analysis of curved beam given in Technical Report 25-26 has been extended to include the effect of antisymmetrical mode. It is shown that when the axial com¬pressive stress becomes four times the Euler critical stress the antisymmetrical mode sets in to aid the snapping action and hence will yield a shorter creep buckling time. The paper also makes an analysis of the behavior of the beam succeeding the snapping action.
