First author proposed a proportioning method for member sections of rigidly jointed single layer reticulated dome subjected to
uniform and non-uniform load without any geometrically initial imperfection, and discussed the validity and effectiveness of the
method which was based on linear buckling stress and a knock down factor. However, the buckling of a single layer reticulated
dome is strongly affected by geometrically initial imperfection. It is well known that geometrically initial imperfections reduce the
nonlinear buckling capacity of a single layer reticulated dome. Thus, structural engineers may be recommended to reflect the effects
of geometrically initial imperfections in proportioning member sections.
In this paper, firstly, the presented proportioning method by first author is applied to dome without consideration of any
imperfections and the thickness and diameter of each member are determined. Secondly, the load bearing capacities of the
proportioned domes are checked with geometrically initial imperfection by the inelastic buckling analysis.
