Load and Resistance Factor Design (LRFD) is a design methodology used in structural engineering to ensure the safety and reliability of structures. It is an alternative to the traditional Allowable Stress Design (ASD) approach. LRFD is widely adopted in many countries, including the United States.

A limit state in structural engineering refers to a condition or state at which a structural system or component can no longer perform its intended function safely and efficiently. It is the point beyond which the structure or component is considered to have reached its design limit and may no longer be capable of carrying the
