Abstract Due to the limitation that probabilistic reliability model has high requirement on original data, convex set model is adopted to describe the uncertain parameters of reliability analysis on compressive bar stability. Then the impact of these uncertain parameters on compressive bar stability response based on convex set model is discussed by one order Taylor series expansion, and the non-probabilistic reliability index of compressive bar stability is presented. This analytic method avoids seeking probability density function, with a lower requirement on original data and simpler to compute.Finally, through computation of engineering case study, this approach is demonstrated to be simple and practical.
