Abstract
The technique of the calculation for probabilistic functions used in the reliability analysis of agricultural structures is proposed in this paper for adapting the standardization method using a numerical intergration. The proposed standardization method deals with the structures whose deviations of material properties and loads are large such that the deviation range from 20% to 70%. The results computed by the proposed method are compared with those obtained by the Monte Carlo Simulation. Deterministic values such as deflection, stress, obtained by conventional structural analysis can be directly changed to probabilistic distributions by the proposed method.
