The present paper focuses on the elasto-plastic buckling loads of the cylindrical reticulated shell roofs. First, an approximate expression for the buckling loads is given based on the classical buckling pressure for continuum cylinders. The linear buckling loads for the reticulated roofs are expressed by use of the classical critical pressure and the reliability of the approximation is comfirmed through exact nonlinear FEM analysis. Second, the elasto-plastic buckling loads for the reticulated roofs are expressed nondimensionally by column buckling in terms of the genralized slenderness ratio which is obtained only by use of the axial buckling stress given from linear buckling analysis and the expression is found to accurately estimate the elasto-plastic buckling loads.
