Fundamentals of LRFR and Applications of LRFR for Bridge Superstructures
Instructor-led Training (ILT)
TRAINING LEVEL: Basic
CLASS SIZE: Minimum: 20 Maximum: 40
This course provides novice and experienced bridge engineers with the fundamental knowledge necessary to apply the most recent AASHTO LRFR Specifications to bridge ratings. This course introduces participants to applications of LRFR specifications that can be used to enhance bridge safety and to identify and discuss the steps to ensure successful transition to this new state-of-the art methodology.
Load Rating of Concrete and Steel Superstructure Bridges will provide participants with in-depth training in evaluating reinforced and prestressed concrete bridges and steel bridges using LRFR methodology. This course will illustrate the use of the current AASHTO evaluation specifications and state-of-the art evaluation methods with step-by-step examples.
Upon completion of the course, participants will be able to:
Describe the purpose of performing a load rating
Identify the benefits of the LRFR methodology
Demonstrate the LRFR process and the general load rating equations
Explain legal loads and their use in load rating
Determine distribution factors for load rating
State the LRFR limit states
Select evaluation factors for rating
Describe the process for load posting and importance of load posting
Describe the procedure for checking overload permits
Demonstrate the application of LRFR requirements by completing load rating exercises
Identify material deteriorations that affect load capacity of bridge components
Calculate the flexural resistances of a prestressed concrete girder for load rating
Calculate the shear resistance of a prestressed concrete girder for load rating
Apply the load rating procedures for concrete slab bridges
Calculate the flexural and shear resistance of a steel I-girder bridge for load rating
Evaluate fatigue for load rating a steel girder bridge
Apply LRFR requirements by completing load rating exercises
Bridge engineers with 0-20 years of experience.
