Axial compressive strengths are determined for lattice columns that are initially wavy in both local and overall modes. When both waviness modes are present, the strength is limited by the onset of divergent amplification of the waviness, with associated reductions in structural stiffnesses. For such divergent but non-bifurcated states of equilibrium, the compressive strength is less than either the classical local or overall buckling strengths. These strength reductions are anticipated to be significant for lightweight space columns of large slenderness ratio, such as the diagonal spars of an 800 meter square solar sailing spacecraft which prompted this investigation.
