For a voluntary Seismic Reinforcement project we installed a matched pair of Simpson® steel moment frames in new grade beams to stiffen the lower floor.
To do this, we had to support the existing structure while we demolished its foundations
San Mateo, CA
To strengthen a seventies-era apartment building, we welded a strap tp the main steel floor beam and bolted it to the existing masonry wall.
It was a quick and simple, but effective, solution. The tenants only had to move their cars for a couple of mornings when most of them were gone anyway.
