The purpose of this paper is to study the dynamic elasto-plastic buckling behaviors of single layered reticular domes. The domes are assumed to be under loadings that a static load proportional to its gravity is followed by a vertical step load with similar distribution of the static case. The analytical models are of about 190 meters span and two cases for 1.5 and 2.0 degrees are investigated for the subtended half angle of members. The nonlinear equations for elasto-plastic vibration of the domes are solved by Newmark's β method. Based on the results of dynamic behaviors are drawn the following conclusions ; (1)the dynamic buckling loads as the additional step load decreases almost linearly to the magnitude of the static load; (2)the differences of buckling loads between the elastic case and the elasto-plastic case are found large for domes with a subtended half angle greater than 1.5 degrees and as well as with a member slenderness less than 90 degrees; (3)in such cases of domes with real dimensions the buckling occurs in elasto-plastic region and the buckling loads are dependent on the yield strength of used materials.
