Abstract
In this paper, the complex nonlinear buckling behaviors of pressurized latticed cylindrical shell roofs affected by geometrical initial imperfections have been investigated. The sectional area of roof members of the adopted latticed cylindrical shell has been designed by dead load. Then the nonlinear numerical experiments for various imperfection amplitudes and modes have been analyzed. Also a simply calculated buckling loads based upon the continuum shell analogy has been represented. This simple design procedure would be useful for the design of linear buckling loads for single layer cylindrical latticed roofs.
