RELIABILITY ANALYSIS OF RHS STEEL TRUSSES JOINTS BASED ON THE P-BOXES APPROACH

Reliability is one of the main indicators structural elements mechanical safety. The choice stochastic models an important task in reliability analysis for describing variability random variables with aleatory and epistemic uncertainty. article proposes a method RHS (rectangular hollow sections) steel truss joints based on p-boxes approach. consist two boundary distribution functions that create area possible variable. using make to model without making unreasonable assumptions about exact cumulative (CDF) or values CDF parameters. developed approach allows give interval estimate non-failure probability joints, which necessary comprehensive (system) entire truss.
