Structural Reliability Theory

Structural Reliability Theory is a field of engineering that assesses the likelihood that a structure—such as a bridge or building—will perform safely during its lifespan. It considers uncertainties in material properties, load conditions, and construction tolerances to estimate the probability of failure. By quantifying risks, engineers can design structures that balance safety and cost-effectiveness, ensuring they can withstand expected stresses and loads without collapsing or malfunctioning. In essence, it provides a systematic way to predict and manage the safety of structures amid unpredictable factors.
