Steel Bridges: Design for Fatigue

COURSE NO: S02-029
PDH CREDIT: 2
COURSE PROVIDER: Donald Parnell, P.E.
Steel Bridges: Design for Fatigue
Course Highlights

This online engineering PDH course provides the practicing engineer with the background required to understand and use the design rules for fatigue resistance that are currently a standard part of design codes for fabricated steel structures. 

 

Fatigue in metals is the process of initiation and growth of cracks under the action of repetitive tensile loading. If crack growth is allowed to go on long enough, failure of the member can result when the uncracked cross-section is sufficiently reduced such that the member can no longer carry the internal forces from the crack which extends in an unstable mode. The fatigue process can take place at stress levels that are substantially less than those associated with failure under static loading conditions. The usual condition that produces fatigue cracking is the application of a large number of load cycles.

 

This 2 PDH online course is applicable to civil and structural engineers and professionals who are interested in learning more about fatigue and the different design standards for fabricated steel structures.
Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Gaining an overview and a historical perspective of fatigue in metals
  • Familiarizing with crack growth and its underlying conditions
  • Learning about the flaws in fabricated steel structures
  • Understanding the load-induced and distortion-induced fatigue
  • Understanding the finite/infinite life design
  • Knowing about fracture control and the AASHTO provisions and specifications
Course Document

In this professional engineering CEU course, you need to review the course document titled, “Steel Bridges: Design for Fatigue”, which is based on the U.S. Department of Transportation Federal Highway Administration document, “Steel Bridge Design Handbook: Design for Fatigue”, Publication No. FHWA-HIF-16-002 - Vol. 12, dated December 2015.

Course Quiz
Once you complete your course review, you need to take a multiple-choice quiz consisting of ten (10) questions to earn 1 PDH credit. The quiz will be based on the entire document.
The minimum passing score is 70%. There is no time limit on the quiz, and you can take it multiple times until you pass at no additional cost.
Certificate of Completion

Upon successful completion of the quiz, print your Certificate of Completion instantly. (Note: if you are paying by check or money order, you will be able to print it after we receive your payment.) For your convenience, we will also email it to you. Please note that you can log in to your account at any time to access and print your Certificate of Completion.
