Summary
| Description |
English:
Seismic retrofit of rectangular column by elliptical steel enclosure with concrete grouting on left subimage. Unmodified column on right.
In this location, not all columns required modification to obtain sufficient seismic resistance in the overall structure. These images were taken in the
BART
Rockridge station western parking lot under State Route 24 eastbound in September 2004. They show two separate
BART
track viaducts and westbound 24 in background.
