NOTES TO DESIGNERS AND DETAILERS

1. Splice lengths shown In TABLES 3.0-60 thru 5.0-60 on 40-D-60004 are for Class B tension lap splices in accordance with AC! 318 and AC! 350. Assumed conditions for these tables in addition to the requirements shown on this drawing are uncoated reinforcement, 2.

normal weight concrete, and the transverse reinforcement index (K,,) equal to zero. Splices or development lengths other than those shown in the tables must be detailed on the reinforcement specifications drawings.

Some factors which require additional consideration are: Beams or columns with ties, lightweight aggregate concrete, epoxy-coated reinforcement, excess reinforcement, bars in compression, bundled bars, and special seismic provisions.

The minimum centerline to centerline bar spacing requirements shown in TABLES 3.0-60 thru 5.0-60 on 40-D-60004 may not be applicable when using the provisions of AC! 350 Section 10.6 for distribution of flexural reinforcement to control flexural cracking.

Recalculation of lap splice lengths and development lengths by the designer may be required for changes in combinations of controlling variables per AC! 318 Section 25.4, or AC! 350 Section 12.2.

Lap splices and development lengths for horizontal bars in walls are designated as top bar splices and development lengths unless otherwise noted or detailed on the reinforcement specifications drawings.

Development lengths for deformed bars in tension terminating in a standard hook shall be calculated by the designer in accordance with AC! 318 Section 25.4.3.1 or AC! 350 Section 12.5. In cases where a restricted member thickness does not allow for the full development length of a standard hook, the designer shall use a reduced tensile capacity.

CONCRETE OUTLINE GENERAL NOTES

CHAMFER:

Chamfer edges of permanently exposed concrete surfaces, except slabs and top edges of curbs, with a 45° bevel,¾" x ¾'1, unless otherwise shown on the specifications drawings.

CONCRETE PLACEMENT :

Before placing concrete, see specifications and manufacturer's drawings, for all embedded material which is required in the placement.

DIMENSIONS :

All dimensions to a joint are to the centerline of the joint unless otherwise shown.

Dimensions to beams, columns, and walls are from reference lines or other control points.

Beam and slab depths shall be measured from the top of the structural slab.

Dimensions given for the depth of recesses are from the surface of the structural concrete.

Thicknesses shown for walls and slabs placed against soil or rock are minimum dimensions.

EMBEDDED MATERIALS:

Before placing concrete, care shall be taken that all embedded items are in position and securely fastened in place. Anchor bolt locations and settings are shown on the structural steel, miscellaneous metal, concrete, and equipment drawings. Conduits and grounding cables are shown on the manufacturer's drawings and the electrical drawings.

All projecting items, including waterstops, shall be supported and protected from damage and exposure.

FINISHES:

For location and classes of finishes for formed and unformed concrete surfaces, see the specifications drawings and/or paragraphs.

JOINTS:

All construction joints, identified as CJ, shall be provided where shown on the drawings. All optional construction joints, identified as OCJ, are to reduce the volume of placements or to facilitate construction. If optional joints are provided they shall be only at the locations shown.

Relocation, addition, or elimination of construction joints will be subject to approval.

TOOLED EDGES :

Tool exposed edges of slabs and top edges of curbs to a radius of ¼", unless otherwise shown on the specifications drawings.

REINFORCEMENT GENERAL NOTES (See Note 4J

ACCESSORIES :

Bar supports, spacers, and other accessories are not shown on the design drawings. The recommendations of the AC! Detailing Manual-2004 (SP-66), or other approved supporting systems shall be used.

CODE AND DETAILING REFERENCES :

AC! Building Code Requirements for Structural Concrete (AC! 318-14).

AC! Detailing Manual-2004 (SP-66).

AC! Code Requirements for Environmental Engineering Concrete Structures (AC! 350-06).

COVER:

Place the reinforcement so that the clear distance between face of concrete and nearest reinforcement is 2" for #8 bars and smaller, and 3" for #9 bars thru #11 bars, unless otherwise shown on specifications drawings. Provide 3" clear distance from face of concrete for all bars when concrete exposure is cast against and permanently in contact with the ground. For corner bars cover, see

ADDITIONAL REINFORCEMENT OPENINGS AND RECESSES, SECTION

A-A on 40-D-60004. Clear distance is to the design dimension line.

Reinforcement parallel to construction joints shall have a minimum of 2" clear cover.

DIMENSIONS :

Dimensions are to the centerline of the bars except for embedment of hooks, which are dimensioned to the outside of the bar.

Clear cover dimensions are marked 11clr. 11 and are dimensioned to the outside of the bar.

PLACING:

Reinforcement at small openings (Max. 1 '-6") in walls and slabs may be spread apart not more than 1.50 times the bar spacing.

Reinforcement shall be adjusted laterally to maintain a clear distance of at least 1" between the reinforcement and keys, waterstops, anchor bolts, form ties, conduits, and other embedded materials.

In heavily reinforced areas, relocation of the embedded material or cutting of reinforcement must be approved.

When bars are bent due to offsets less than 3" and recesses less than 3" deep, the slope of the inclined portion must not exceed 6 to 1.

Reinforcement parallel to anchor bolts or other embedded material shall be placed to maintain a clear distance of at least 1.33 times the maximum size aggregate.

PLAIN DOWELS :

Plain dowels across contraction joints shall be smooth bars uniformly coated with a film of oil before concrete placement.

REINFORCEMENT DOWELS:

Unless otherwise shown, dowels indicated on the drawing, such as

#8(d), shall be embedded a length equal to f,,i and shall have a projection equal to that required for lap splicing to a bar of the same diameter.

SPACING:

The first and last bars in walls and slabs, stirrups in beams, and ties in columns are to start and end at a maximum of one half of the adjacent bar spacing. The minimum edge spacing shall be 2.5db.

For #9 thru # 11 bars where minimum centerline bar spacing is 6" and the lap splice lengths requiring staggered placement shown in TABLES 3.0-60 thru 5.0-60 on 40-D-60004 are used, the minimum edge spacing shall be 3".

I 4

SPUCES:

The minimum length of lap for splicing parallel bars in tension shall be as given in TABLES 3.0-60 thru 5.0-60 on 40-D-60004.

Staggered lap splices shall be separated to give 12 inches clear between ends of adjacent splices.

Bars spliced by noncontact lap splices shall not be spaced transversely farther apart than one-fifth the required lap splice length, nor 6" on centers.

When reinforcing bars of different size are to be spliced, splice length shall be the larger of f,,i of larger bar and tension lap splice length of smaller bar.

Splices are to be made so that the required clear distances to face of concrete will be maintained.

STANDARD HOOKS FOR DEVELOPMENT OF DEFORMED BARS IN

TENSION:

90-degree bend plus 12db extension at free end of the bar.

180-degree bend plus 4db extension, but not less than 2½", at the free end of the bar.

STANDARD HOOKS FOR STIRRUPS, TIES, AND HOOPS :

#5 bar and smaller, 90-degree bend plus 6db extension, but not less than 3", at the free end of the bar.

#6, #7, and #8 bars, 90-degree bend plus 12db extension at the free end of the bar.

#8 bars and smaller, 135-degree bend plus 6db extension, but not less than 3", at the free end of the bar.

#8 bars and smaller, 180-degree bend plus 4db extension, but not less than 2.5", at the free end of the bar.
