Moment Frame Retrofit:

This moment frame was just fabricated and installed in San Francisco, CA.  The seismic retrofit was required by the city as part of an upgrade during the home owner’s renovations.  The beam was 800lbs and lifted into place by five men.  The column was 11 feet long at a height of 96 inches.

Moment Frames can be welded on the job site or in the shop.  NorCal Welding had the steel delivered to this job site so we could do the welding on site.  Our welders are D1.8 certified for seismic retrofit welding.
