Development of Alternate Load Paths Around Blast or Cut Damaged/Destroyed Steel Truss Members

Project Information

Project ID:
FHWA-PROJ-13-0043
Project Abstract:

This research is being conducted to study the ability of steel truss bridges to use alternate load paths when damaged, preventing total or immediate collapse of the structure. 


Goals:

  • Assessment of steel truss bridge existing members' ability to provide full or partial redundancy/alternate load paths (ALPs) to prevent progressive collapse from blast loads or member cutting. 
  • Assessment of currently used seismic retrofit designs' ability to provide ALPs to prevent progressive collapse of Steel Truss bridges from blast loads or member cutting. 
  • Initiate development of bridge retrofit components to provide full or partial redundancy/alternate load paths to prevent progressive collapse of steel truss bridges caused by local blast failure or by cutting of individual members.
