BEAM NOTES
1.
All bar dimensions are out-to-out.
2. Strands N (Dormant Strands) shall be either ASTM A416, Grade 250 or
Grade 270, seven-wire strands " \ or larger, stressed to 10,000 lbs. each.
3.
Unless otherwise noted in Structures Plans, the minimum concrete cover
for reinforcing steel shall be 2".
4. At the option of the Contractor and with the Engineer’s Approval, deformed
welded wire reinforcement may be used in lieu of Bars 6A1, 4A2, 5B, 4C, 3D,
5E, 4F, 4G, 4H, 5K, 5L and 4M except as noted below in note 7, provided the
wire sizes and spacing match those shown on the Standard Beam Detail sheets
for these bars. Welded wire reinforcement shall conform to ASTM A497.
5. Place 2" NPS x 5"
PVC Sch. 40 Safety Sleeve with cap in both top flanges
spaced on 8’-0" (Max.) centers.
Shift Bars 5K & 4M locally to allow placement.
Holes shall be free of debris and water prior to casting deck.

6. For Beams with vertically beveled end conditions when "DIM. P" exceeds 1",
Temporary Blocking (See
Composite Neoprene
Note 12) (Typ.)
Bearing Pad
Bars 5E and the first Bars 4F and 5K shall be placed parallel to the end of
the beam. The remaining Bars 4F and 5K within the limits of "DIM. B" shall
be fanned at equal spaces.
7. Welded deformed wire reinforcement shall not be used for the end reinforcement
(Bars 5B, 4C, 3D, 5E, 4F, 5K, and 5L) for beams with skewed end conditions
Pedestal
or vertically beveled end conditions when "DIM. P" exceeds 1".
8.
Pier/Bent Cap
Bars 5K shall be placed and tied to the fully bonded strands in the bottom
row (see "STRAND PATTERN" in Structures Plans).
9.
Strand Protection at beam ends shall consist of a 2" deep recess formed
around all strands (including dormant)
or strand groups.
Extend recess to
face of web and bottom of flange for bottom row of strands.
After
detensioning, cut strands " from recessed surface and fill the recess with
a Type F-2 or Q Epoxy Compound in accordance with Section 926 of the
TEMPORARY BLOCKING OF BEAM ENDS
Specifications.
10. Use Size No. 67 maximum sized aggregate.
11.
Use Stay-in-Place metal deck forms inside the beams.
12.
Prior to deck placement, based on the deck forming system and deck placement
sequence, evaluate and provide, if necessary, temporary bracing between the U Beams.
End of Beam

Ensure the temporary blocking is adequate to resist movements and
Leave temporary blocking and bracing
in place for a minimum of four days after the deck placement.
