2107.2 TMS 402/ACI 530/ASCE 5, Section 2.1.7.7.1.1, Lap Splices. I

2014 FBC - Building, 5th edition > 21 Masonry > 2107 Allowable Stress Design > 2107.2 TMS 402/ACI 530/ASCE 5, Section 2.1.7.7.1.1, Lap Splices. I
JUMP TO FULL CODE CHAPTER
n addition to Section 2.1.7.7.1.1, it shall be permitted to design lap splices in accordance with Section 2107.2.1.

2107.2.1 Lap Splices

The minimum length of lap splices for reinforcing bars in tension or compression, ld, shall be

ld = 0.002db fs(Equation 21-1)
For SI: ld = 0.29db fs
but not less than 12 inches (305 mm). In no case shall the length of the lapped splice be less than 40 bar diameters.
where:
db=Diameter of reinforcement, inches (mm).
fs=Computed stress in reinforcement due to design loads, psi (MPa).
In regions of moment where the design tensile stresses in the reinforcement are greater than 80 percent of the allowable steel tension stress, Fs, the lap length of splices shall be increased not less than 50 percent of the minimum required length. Other equivalent means of stress transfer to accomplish the same 50 percent increase shall be permitted. Where epoxy coated bars are used, lap length shall be increased by 50 percent.
