Steel Frame Building Retrofit Services We Offer:

Optimum Seismic’s team of structural engineering and construction experts have decades of experience in providing full-service structural retrofits of steel frame buildings.

By retrofitting your steel moment frame building, Optimum Seismic is able to strengthen weakened connections, protect your property against future seismic events and safeguard your equity. Our structural framing contractors can apply alternatives solutions during retrofit construction, depending on your type of buildings and the severity of the defects.  These alternatives include:

  • Strengthen the connection locally with beam-to-column connections or chevron bracing
  • Adding dampers or a lateral system to strengthen the steel moment frames

Steel frame buildings constructed before the mid-1990s can sustain brittle fracturing of steel frames at welded or riveted joints between the beams and columns, which can damage or break connections and create the potential for localized collapse.

Failures of these structures were common during the 1994 Northridge quake. Many other buildings developed fracturing as a result of the seismic shaking. Still others have yet to undergo an analysis to determine if fracturing has occurred, or to assess their ability to withstand another major quake.

Steel moment frame building retrofits can help ensure your building is secure during future seismic events, and prevent injury or loss of life for tenants and pedestrians.
