Introduction to Structural Reliability and Safety Engineering

How do we ensure that bridges, buildings, and offshore platforms remain safe under unpredictable loads and environmental conditions? Understanding structural reliability is essential for modern civil and structural engineers who must balance safety, performance, and cost. This course introduces you to the core principles of probability and risk assessment used to evaluate structural integrity over time. You will transition from deterministic design concepts to modern probabilistic safety methods, learning how to model uncertainties in material properties, loading conditions, and environmental demands. Through clear, written explanations and practical engineering scenarios, you will develop the skills to calculate failure probabilities and implement reliable design standards. What you'll learn: - Understand foundational concepts of probability, random variables, and limit state functions in structural design - Analyze uncertainties in material strength, structural dimensions, and external loading conditions - Apply First-Order Reliability Methods (FORM) to calculate structural reliability indices - Evaluate system reliability for series, parallel, and redundant structural configurations - Practice assessing lifetime structural performance and degradation under environmental stress - Implement risk-informed decision-making processes to align with modern engineering safety codes This text-based course begins with essential mathematical and probabilistic foundations before guiding you through limit states, reliability index calculations, and system-level risk assessments. You will study practical scenarios that mirror real-world engineering challenges, all explained step-by-step through clear text and structured examples. This course is designed for undergraduate engineering students, practicing structural engineers, and civil engineering graduates who want to build a strong foundation in reliability analysis. No prior background in advanced probability is required, as all foundational concepts are explained from the ground up.
