Patient Details
A mandatory soft story seismic retrofitting project was completed for compliance in Los Angeles. The structural reinforcement involved excavating three new 20-inch by 33-inch grade beam footings spanning approximately 63 feet at three garage bays, along with four pad footings. Three new offset cantilevered wide flange W columns (W12x45 and W14x48) were installed and bolted to the newly poured pad footings. The grade beams were poured using a minimum of 4000 PSI concrete. Additionally, the structure was reinforced by installing 4x blocking and 1/4-inch by 4-inch partitioned steel drag plates across the easterly and northerly diaphragms , secured with A35 and LTP5 framing anchors.
