Abstract
The study concerns the static analysis of rods structures in terms of probabilism. Structural design parameters are defined as the deterministic values and random variables. Random variables are not correlated. The criterion for structural failure is expressed the limits of functions referring to the ultimate and serviceability limit state. The Cornell and Hasofer-Lind index is used as a reliability measure. The primary research method is the FORM method. In order to verify the correctness of the calculation SORM, Monte Carlo and Importance Sampling methods are used. The sensitivity of reliability index to the random variables is defined. The STAND program is used to present the examples of reliability analysis.
