Repair and Retrofit of Fatigue Cracks in Steel Bridges

$75.00

Students will learn about fatigue and fracture, two of the states of steel bridges that are the least understood when it comes to design, inspection, and repair and retrofit. They will also learn the driving causes of fatigue cracking and fracture and how understanding these concepts can help with maintaining the structural integrity of the bridges for the safety of the millions of using them.

Description

Course Objectives:

  1. Students will learn about fatigue and fracture, two of the states of steel bridges that are the least understood when it comes to design, inspection, and repair and retrofit. They will also learn the driving causes of fatigue cracking and fracture and how understanding these concepts can help with maintaining the structural integrity of the bridges for the safety of the millions of using them.
  2. Student will recognize the difference of how a repair is intended to arrest the propagation of a fatigue crack, while a retrofit is intended to upgrade the fatigue resistance and prevent fatigue cracking, which is important to understand for maintenance and soundness of the bridge.
  3. Student will be learn about secondary stresses which may impact the structural integrity of the bridges or could cause traffic disruption.
  4. Student will be presented design examples to show how different retrofit may be specified and how to determine the remaining fatigue life.
