A stochastic approach to estimate the elastic buckling strength of truss structures is developed by combining the bifurcation and probabilistic theories, and applied to the actual data of a truss dome structure. According to the data of the initial imperfection of truss members, which can be regarded as statistical variables, the analytical expression for the probability density function of the strength of the overall structure is obtained together with several parameters that canbe determined by a few computations. The applicability of the approach is evaluated in the context of structural design and its feasibility is compared with the result by Monte-Carlo simulation.
