Theory

These pages explain the formulations, assumptions and limitations behind PySTRA’s reliability algorithms and engineering workflows. Begin with the fundamentals and probability transformations, then consult the method you are using. Notation and probability spaces defines coordinates and reliability indices. Worked applications are organized in Examples.

• Structural reliability fundamentals
• Probability transformations and copulas
• FORM, SORM and design-point diagnostics
• Simulation methods
• System reliability
• Load combinations and FBC processes
• Code calibration using normalized reliability
• Design decisions and societal risk
• Active-learning reliability
• Reliability sensitivity
