The elasto-plastic dynamic buckling behavior of rigidly jointed single layer lattice domes under vertical and horizontal step wave has been analytically investigated in this paper. A step wave is a simple one whose response spectrum curve is horizontal line. Therefore, the buckling behavior of domes under dy namic loads can be easily grasped. From the numerical results, we have examined the time histories of responses, the dynamic buckling loads, the input energy and the strain energy and so on. Based on the above examinations, the effects of the half subtended angle of dome, input direction of step wave on the dynamic buckling behavior will be discussed.
