As per ACI 318, the tension lap splices are classified into two classes Class A and Class B ( Table R12.5.2, ACI 318) for which the lap length are as follows: Class A Splice: Lap Length ls = 1.0 ld. Class B Splice: Lap Length ls = 1.3ld
Nov 3, 2017 · The lap length is equal to the development length calculated in compression but not less than 24d. For Different Diameter Bars: When the bars of different diameters are to be spliced, the lap length is calculated considering the smaller diameter bar.

Jul 29, 2017 · 1. Basic Lap Length Formula: This simplified method often serves as a preliminary estimate: Lap Length (L) = 50d. Where: d = Reinforcement diameter (mm) This formula assumes standard lap splices in normal concrete conditions. 2. Code-Based Calculations:
Dec 2, 2020 · A handy online tool to quickly compute the rebar development length to ACI code in SI metric units. December 2, 2020 by CCStruct. This online tool lets you calculate the tension and compression development length of a deformed reinforcing bar.
Lap splices of bundled bars should be based on the lap splice length recommended for individual bars of the same size, and individual splices within the bundle should not overlap each other. The length of lap should be increased 20% for a three-bar bundle and 33% for a four-bar bundle.
Splices for No. 11 bars and smaller are usually made simply by lapping the bars in a sufficient distance to transfer stress by bond from one bar to the other. The lapped bars are usually placed in contact and lightly wired so that they stay in position as the concrete is poured. fy fs = 0.
Lap length or overlapping length is the length at which two bars of a column are spliced or overlapped in order to maintain the continuity of the bars throughout the length of the column. This method of overlapping two reinforcement bars is called lap splicing.
DETAILS OF CALCULATION. Notation and methodology according to clause 8.7 of EC2. Good Bond conditions. 1) Tensile bar. l 0 (Lap length) = 488 mm. l 0 = α 1 · α 2 · α 3 · α 5 · α 6 · l b,rqd ≥ l 0,min. where: l b,rqd (basic required anchorage length) = 484 mm. l b,rqd = (Φ / 4) (σ sd / f bd) with: σ sd = r · f yk /γ s = 1·500/1.15 = 434.78 MPa.
