FHWA-NHI-130078 Bridge Inspection Techniques for Nonredundant Steel Tension Members (NSTM) MTS New


This course is intended to supplement participant's existing knowledge with bridge inspection techniques by increasing their depth into the inspection of Non-Redundant Steel Tension Members (NSTMs). The course includes hands-on demonstrations of common nondestructive evaluation (NDE) methods that inspectors may use during inspection of NSTMs, development of a NSTM bridge inspection plan procedure, and updated activities that maximize participant engagement throughout the course.

The first day of the training focuses on the definition of NSTMs, NSTM identification, properties of steel, weld types and quality, load-inducted fatigue, distortion induced fatigue, and fracture.

Day two includes fatigue prone details, AASHTO fatigue categories along with hands-on exercises to identify fatigue details with three-dimensional models. Day two concludes with planning and executing an NSTM inspection with lessons covering hands-on access, field evaluation of findings, critical findings, and developing NSTM inspection procedures.

Day three covers nondestructive testing methods with a description of ultrasonic, magnetic particle, and dye penetrant testing methods. Participants will also get hands-on experience conducting both magnetic and dye penetrant testing on real welds.

Target Audience:

The primary audience of this course is public and private sector engineers, inspectors, and others responsible for field inspection of NSTMs. This course is intended for those that have completed the bridge inspection training (FHWA-NHI 130055/55C, 130056/55C or similar) and are currently inspecting bridges or are part of a bridge inspection program.


Upon completion of the course, participants will be able to:

  • Define NSTM, fatigue, and fracture
  • Identify properties of steel
  • Discuss weld types and quality
  • Describe factors affecting fatigue life
  • Identify distortion-induced fatigue
  • Explain constraint-induced fracture
  • Identify fatigue categories and details
  • Discuss NBIS requirements for NSTM inspections
  • Describe steel defects and effect on fatigue
  • Prepare NSTM inspection procedures given abridge example
  • Evaluate NDE methods

Note: Food is not provided, please plan accordingly.
