The present paper discusses the effects of the joint rigidity on the buckling strength of single layer reticular domes on a circular plan. The domes are assumed under uniform vertical loading. The effects are clarified mainly from the following view-points ; (1)how the joint rigidity reduces the elastic buckling loads, (2)how the reduction can be interrelated to column strength curves in terms of the generalized slendemess ratio for the member most relevant to the overall buckling of domes, (3)whether the column strength curves will resemble those for beam-columns in tall buildings or those for continuum shells, or will not. The discussions conclude that (1)modification of the generalized slendemess ratio- by reflecting the joint rigidity leads an almost same column strength curve for rigidly jointed members and (2)the elasto-plastic buckling loads for domes with semi-rigid connections can be estimated by applying the modified slendemess ratio.
