Steel Bridge Design Handbook: Limit States

In the American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) Bridge Design Specifications, a limit state is defined as “a condition beyond which the bridge or component ceases to satisfy the provisions for which it was designed.” Bridges designed using the limit-states philosophy of the LRFD Specifications must satisfy “specified limit states to achieve the objectives of constructibility, safety and serviceability.” These objectives are met through the strength, service, fatigue-and-fracture and extreme-event limit states. This module provides bridge engineers with the background regarding the development and use of the various limit states contained in the LRFD Specifications.
