The experience indicates that the most common reason of the construction or assembly incoherency are not really irregular outside loads or influences but unpredictable standard behaviour of the bolted joints. Incorrect application or design of the bolted joints can lead to catastrophic accidents. The most common mistakes are under-sizing or inappropriate over-sizing, ignoring the fatigue, creep or anticorrosion protection. Bolted joints are in their working conditions exposed to action of internal or external forces with a different magnitudes and orientations. Presented article should provide a basic guide how to set certain loads acting on the bolted joint and calculate the reliability of the bolted joint considering the probabilistic approaches. In order to capture random variables in design and validation stage of the bolted joints, Simulation Based Reliability Assessment (SBRA) using Monte Carlo method is presented.
