The present work proposes a knock down factor which can be used in esti mating elasto-plastic buckling loads as well as in proportioning members of reticulated domes based on consideration of shall-like buckling. In the first part, a discussion is made on how the knock down factor is derived based on an analysis of shell-like buckling of reticulated domes using past, various elasto-plastic buckling results covering vast geometries and boundary conditions . In the second part, several domes designed based on the analysis are verified to satisfy the required ultimate loads required in design stage.
