Reinforce Building With Steel Moment Frames

Lateral bracing can be employed through the use of a steel moment frame which allows the open space to be maintained and eliminates the need for infilling openings or additional crosswalls. A steel moment frame is composed of beams and columns welded at their joints and connected to the floor above the open area.

Effectiveness:

  • Very effective.
  • Consider crosswalls for maximum effectiveness.

Limitations:

  • Steel moment frame must be adequately connected to the new footing and to the structure.
  • Field welding of the frame components is necessary and a new footing for the frame must be added. 

 

 

NOTE:  None of the mitigation measures in these Handbooks should be considered ‘pre-approved’ or otherwise automatically eligible for FEMA funding. Only FEMA staff can determine eligibility, once they have determined that an applicant is eligible and they have reviewed a project proposal.
