NOTES:

1. SEE "REINFORCING BENDS IN CONCRETE" DETAIL FOR ADDITIONAL

INFORMATION.

2. TABULATED DEVELOPMENT LENGTHS ARE BASED ON REINFORCEMENT STEEL

YIELD STRENGTH (Fy = 60 KSI) AND NORMAL WEIGHT CONCRETE.

3. ALL TABULATED VALUES ARE MINIMUM LENGTHS, IN CASE OF CONFLICT WITH

PLANS, SECTIONS, OR DETAILS, USE THE LONGER LENGTH.

4. db = BAR DIAMETER.

5. Ldh = TENSION DEVELOPMENT LENGTH (HOOKED BARS).

6. MULTIPLY TABULATED LENGTHS BY THE FOLLOWING FACTORS WHERE

APPLICABLE. NOTE THAT THE FACTORS ARE CUMULATIVE: (E.G. 1.33x1.50 = 2.0)

A. REINFORCEMENT BAR STRENGTH

OTHER THAN 60 KSI: (Fy / 60,000)

B. LIGHT WEIGHT CONCRETE: 1.33

NOTES:

1. REFER TO "HOOKED REINFORCEMENT TENSION DEVELOPMENT LENGTH SCHEDULE"

WHEN THE STRAIGHT DEVELOPMENT LENGTH IN TENSION CANNOT BE

ACCOMODATED IN THE CONCRETE SECTION.

2. ALWAYS USE TENSION DEVELOPMENT LENGTH AND LAP SPLICE LENGTH VALUES.

3. TABULATED DEVELOPMENT AND LAP SPLICE LENGTHS ARE BASED ON REINFORCING

STEEL YIELD STRENGTH Fy=60 KSI, NORMAL WEIGHT CONCRETE, AND CLASS B LAPS.

4. TOP BARS ARE DEFINED AS HORIZONTAL BARS WITH MORE THAN 12 INCHES OF

FRESH CONCRETE CAST IN THE MEMBER BELOW THE BARS TO BE DEVELOPED OR

SPLICED. TOP BAR FACTOR APPLIES TO HORIZONTAL BARS IN WALL.

5. WHEN DIFFERENT BAR DIAMETERS ARE SPLICED, USE LARGER BAR LAP SPLICE

LENGTH.

6. ALL TABULATED VALUES ARE MINIMUM LENGTHS, IN CASE OF CONFLICT WITH

PLANS, SECTIONS, OR DETAILS, USE THE LONGER LENGTH.

7. db = BAR DIAMETER.

8. ld = DEVELOPMENT LENGTH.

9. ls = LAP OR SPLICE LENGTH.

10. ADJUST TABULATED LENGTHS BY THE FOLLOWING FACTORS WHERE APPLICABLE.

NOTE THAT THE FACTORS ARE CUMULATIVE: (E.G. 1.30x1.50 = 1.95) A. CLEAR SPACING LESS THAN 2b

AND CLEAR COVER LESS THAN db: 1.50

B. CLASS A LAP SPLICE 0.77

C. EPOXY COATED BARS: 1.50

11. WELDED AND/OR MECHANICAL SPLICES MAY BE USED IF APPROVED BY THE

CONTRACTING OFFICER OF RECORD PROVIDED THAT THE SPLICE IS CAPABLE OF

DEVELOPING AT LEAST 125% OF THE YIELD STRENGTH OF THE LARGER BAR IN

TENSION. WHERE WELDED AND/OR MECHANICAL SPLICES ARE TO BE USED, THE

GENERAL CONTRACTOR SHALL SUBMIT FULL DATA ON THE PROPOSED MATERIAL,

PROCEDURES, AND INSTALLATION INSTRUCTIONS TO THE CONTRACTING OFFICER

FOR REVIEW AS A SHOP DRAWING SUBMISSION.

12. USE MECHANICAL COUPLERS FOR #14 AND LARGER BARS.

13. LAP SPLICES IN CONCRETE MASONRY SHALL BE AS SPECIFIED IN "STRAIGHT

REINFORCEMENT DEVELOPMENT AND LAP SPLICE LENGTH IN GROUTED MASONRY"

DETAIL.

14. SPLICES OF HORIZONTAL REINFORCEMENT IN WALLS SHALL BE STAGGERED.

15. SPLICES IN WALLS CONTAINING TWO CURTAINS OF REINFORCEMENT SHALL NOT

OCCUR IN THE SAME LOCATION.
