Notes:
1. At beam ends use 1" deep recesses around local strand groups
with 2" minimum edge clearances and fill with pneumatically applied
mortar immediately after clipping strands. An approved epoxy
mortar covering the ends of strands with a minimum thickness of
" may be used as an alternate. Strands should be cool before
mortar is applied. After mortar is allowed to cure, the entire
end of beam shall be covered with epoxy type EP-3T.

PRESTRESSED CONCRETE BEAM
AASHTO TYPE VI
CONTINUOUS SPAN
NOTES TO DESIGNER:
Standard is to be used for simple span, AASHTO Type VI prestressed concrete beams, made
continuous for composite dead load and live load plus impact.
Include standard PCB-MISC (Miscellaneous Beam Details) in the plans when using this standard.
End details (Plan) show typical beam ends with end diaphragm on left and closure diaphragm on
right for 0° skew.
SECTION ON CENTERLINE shows two stud shear connectors (total 4). Designer must check for
required number and modify this sheet as needed and have it agree with the bearing standard
sheet.
Details shown for typical beam end at closure diaphragm are for positive moment connections
designed in accordance with the procedures outlined in the August 1969 PCA Engineering
Bulletin “Design of Continuous Highway Bridges with Precast, Prestressed Concrete Girders”.
The designer shall ensure that bar BS0403 projects beyond the top flange of beam to mid-depth
of deck slab when determining the dimension “G”.
The designer shall coordinate the location of diaphragm inserts and web through holes with that
of draped strands to avoid conflicts. Adjust location of diaphragms as required.
ADD THE FOLLOWING NOTES, DIMENSIONS, DETAILS, ETC. TO STANDARD:
PLAN:
Modify end detail(s) when skew is not 0 and/or the actual end condition(s) differ from what is
shown on the standard sheet.
SECTION ON CENTERLINE:
Modify end detail(s) as needed when actual end condition(s) differ from what is shown on the
standard sheet.
Complete the vertical stirrup details for end of beams. Modify bar sizes as needed.
END VIEW and SECTION A-A:
Complete details for strand pattern (spacings) for both details with low-relaxation strands.
