Steel Bridge Design - Limit States
Credits: 2 PDH
PDH Course Description:
This course on limit states is focused on describing the different types of limit states that must be considered in the design of a steel bridge. Limit states are defined as the conditions or events that, if they occur, can result in the failure of a structure. In bridge design, limit states are divided into two categories: service limit states and ultimate limit states. This course describes in detail the different types of ultimate limit states, such as flexural yielding, local buckling, lateral-torsional buckling, and fracture. The different types of loads that can cause these limit states to occur, such as dead loads, live loads, and wind loads, are also discussed.In addition, are the different design methodologies used to ensure that a steel bridge meets the required limit states. The Load and Resistance Factor Design (LRFD) method is the preferred approach for steel bridge design in the United States. The LRFD method allows for a more accurate determination of the loads and their effects on the bridge, resulting in a safer and more efficient design. Overall, the course on limit states in the FHWA Steel Bridges Handbook provides a comprehensive overview of the different types of limit states that must be considered in the design of a steel bridge. It emphasizes the importance of selecting the appropriate design methodology and ensuring that the bridge meets all required limit states to ensure the safety and durability of the structure.
