APRIL 2015 ASCE/SEI JOINT MEETING REVIEW

The 11th Street Bridge - Successful Re-sequencing During Construction


Thanks to Shane Beabes, PE and Raghu Krishnaswamy, PE of AECOM for their presentation!

The presentation focused on the complexities of the 11th St. Bridge Project in Washington DC.  Some highlights include:

  • the iterative nature of analysis when the design-build environment dictates alternative construction sequences (i.e. single stage construction vs. multi-stage construction) after girder fabrication has taken place,
  • the use of counterweights to enable fit-up and alleviate locked-in stresses,
  • the implementation of lean-on bracing to resist compression flange buckling.


Thanks again, Shane and Raghu!
