The whole process of load-deflection response is analyzed for two single-layer lattice dome of big size as practical examples. The nonlinear behaviours of the perfect domes and their deflection shapes at several points after buckling are at first investigated. Two methods for imperfection analysis are then suggested. It is proved that single-layer lattice dome is very sensitive to initial imperfections and the suggested methods can be applied to real analysis.
