2107.2.3 ACI 530/ASCE 5/TMS 402, Section 2.1.10.6.1.1, Lap Splices

NYC Building Code 2008 > 21 Masonry > 2107 Working Stress Design > 2107.2 Modifications to ACI 530/ASCE 5/TMS 402 > 2107.2.3 ACI 530/ASCE 5/TMS 402, Section 2.1.10.6.1.1, Lap Splices
JUMP TO FULL CODE CHAPTER
The minimum length of lap splices for reinforcing bars in tension or compression, lld, shall be calculated by Equation 21-2, but shall not be less than 15 inches (381 mm).

(Equation 21-2)

For SI: lld = 1.95d2bfyλ / K√f'm
where:
db = Diameter of reinforcement, inches (mm).
ƒy = Specified yield stress of the reinforcement or the anchor bolt, psi (mPa).
ƒ'm = Specified compressive strength of masonry at age of 28 days, psi (mPa).
lld = Minimum lap splice length, inches (mm).
K = The lesser of the masonry cover, clear spacing between adjacent reinforcement or five times db, inches (mm).
γ = 1.0 for No. 3 through No. 5 reinforcing bars. 1.4 for No.6 and No.7 reinforcing bars. 1.5 for No.8 through No. 9 reinforcing bars.
