Post-Failure Capacity Of Built-Up Steel Members, Matthew H. Hebdon
Post-Failure Capacity Of Built-Up Steel Members, Matthew H. Hebdon
Purdue Road School
Mechanically fastened built-up steel members have long been known to possess internal member redundancy and, as a result, multiple load paths which can be exploited to increase their functional life. Internal redundancy provides the ability to resist total member failure in the event of a fracture of an individual component. However, there is little experimental data in the literature regarding post-fracture capacity in terms of strength and subsequent fatigue life. The experimental study currently underway will provide needed information on parameters that affect the ability of built- up members to arrest a fracture as well as the available remaining fatigue …

Post-Fracture Capacity Of Railroad Flat Car Bridges, Teresa L. Washeleski
Purdue Road School
Railroad flatcars (RRFCs) are a convenient option to replace existing deteriorating bridge structures on low-volume roads. They are typically used as the bridge superstructure by placing two or more flatcars side-by-side to achieve the desired bridge width. Utilizing RRFCs as a bridge allows for rapid construction and greater cost savings compared to traditional practices. These benefits make them an attractive solution for rural communities in Indiana, as well as other states.
Uncertainty remains about the response under higher loads than could be easily achieved in the field and the level of redundancy of railroad flatcar bridges. Using RRFCs as bridges …

2014 Road School, Kevin M. Hetrick
Purdue Road School
At the 2014 Road School, this presentation focused on the proposed sliding of the Milton-Madison Bridge, a 15000 ton truss superstructure intended to move laterally 55 feet from a temporary location onto permanent piers. The project was a joint procurement between INDOT and KYTC, with a Design/Build team consisting of Walsh Construction, Buckland and Taylor, and Burgess and Niple performing the slide. The presentation was in early March, with the slide scheduled for later in the month. The slide will be the largest of its kind.
