The manufacturing deviation of grids structures was assumed to be in normal distribution
and the normal random sampling was realized by acceptancerejection method. Based on the finite element method and probability method
the initial displacement and stress of grids structures due to manufacturing deviation were analyzed. Numerical example showed that the random manufacturing deviation produced large initial stress
which induced buckling failure of some spatial grid members
and had a large effect on the safety of the grids structures and could not be ignored. It also showed that the method obtained had guiding significance for the design and fabrication of grids structures.
