Sensitivity analysis allows us to investigate the role, the contribution of the input factors to the objective output function. The results of the sensitivity analysis help the designer adjust the reliability of the structures In this research, we investigate the role and the contribution of the input structural parameters to the critical radial load of the symmetry span steel arch, section I. The Sobol' sensitivity analysis and Monte Carlo simulation method have been used to analysis the entire space of input factors. The characteristic of the structural parameters, cross section factors are considered random variables.
