Reliability-Based Design

Reliability-Based Design (RBD) is an engineering approach that ensures structures or systems are safe and dependable by considering uncertainties in materials, loads, and conditions. Instead of aiming for a single "perfect" design, RBD evaluates the probability that a system will perform its intended function without failure over its lifespan. It balances safety and cost by using statistical methods to account for variations, optimizing the design to meet desired reliability levels. Essentially, RBD helps engineers create designs that are both economical and confident in their longevity and safety.
