SFOBB East Span Seismic Safety Project Construct Concrete Seat Extensions, drill and bond dowels Typical Section Near Bent 33 Frame 1 - Typical Section Frame 1 - Typical Section Wall,typ Design Note: Floor beams are simply supported by continuous retaining walls with partial height counterfort walls. Analysis has determined floor beams are vulnerability to unseating.

Analysis has determined inadequate shear capacity of the short columns. Additionally, floor beams are vulnerability to unseating.

Strengthen (encase) longitudinal girder beneath ramp. 4. Strengthen (encase) and tie-down, ramp column footings. 5. Construct seat extension and bolster at ramp abutment diaphram. 6. Extend bent caps to ramp columns. 7. Construct shear wall and retaining walls. Demo and widen deck from bent 41 to just beyond bent 42 (not shown) Design Note: Analysis has identified that the caps and girders are not capable of resisting the column plastic moment.
