• Abstract:
  Steel structures supporting traffic sign panels are designed as intended to dissipate energy by
  
  yielding structural members during severe wind loading (ex. strong hurricanes). Yielding results
  
  in inelastic deformations, which are permanent damage to structural members. Structures with
  
  permanent deformations present the out-of-plumb appearance. Damage might be repairable;
  
  however, deconstruction and replacement of an off-centered structure with a new structure is
  
  usually more economical. If a new design approach that controls damage and avoids replacement
  
  can be developed, the direct and indirect costs of post-extreme-wind repair for traffic sign
  
  supporting structures can be saved enormously.
  
  At present, the design approach mitigating damage for traffic sign supporting structures under
  
  extreme wind loads are undeveloped. This research conducts an exploratory study on the new
  
  design method of “self-centering connections,” termed “SC connections.” The scopes of this
  
  research project are: (1) design equations and criteria development; and (2) validation through
  
  numerical analyses.
