Why Soft-Story Retrofits—and Rebar Cages—Are Critical for Your Building's Safety

Soft-story buildings are common in many urban areas, especially those built before modern seismic codes were adopted. These structures typically have ground or lower floors that are significantly less stiff than the floors above—often due to open spaces used for parking, retail, or office areas. This design flaw makes them especially vulnerable during earthquakes.
A soft-story retrofit strengthens these weak lower levels to prevent collapse in the event of seismic activity. One of the most effective reinforcement methods is the installation of rebar cages. These steel frameworks are embedded in new concrete shear walls or columns, dramatically increasing the building’s ability to resist lateral movement.
Common Signs a Building Needs a Soft-Story Retrofit:
Tuck-under parking with minimal structural support
Open office floors divided only by glass partitions
Ground floors with large glass storefronts and few walls
Without a proper retrofit, these buildings face a high risk of structural failure during earthquakes. By integrating rebar cages into the retrofit plan, the structure gains essential reinforcement at its most vulnerable points.
