WebLap splices, or full mechanical or welded splices can be used to splice spiral reinforcement. Lap splice lengths should comply with Table 9.12, but not be less than 12 in. The ACI 318 Building Code contains provisions for lap splicing bars of different sizes in compression. WebReinforcing bars can also be spliced using end-bearing splices, but only in members containing closed ties, closed stirrups or spirals for bars subject to compression only. End-bearing splices rely on the transmission of compressive stress by bearing of square-cut ends held in concentric contact by a suitable device. WebStaggered Lap Splices. Introduction.

WebRebar couplers or mechanical splices are used to connect reinforcement bars of various grades and diameters. They eliminate the use of lapping and welding. Rebar couplers can join rebars with full tension capacity. The ends of steel bars to be joined are provided with threads, and a coupler is used to join rebars end-to-end, which transfers the ... WebSplices in reinforcing steel are grouped in three categories: lapped bars, mechanical, or welded; the focus of this report is mechanical splices. Strength capacities established in ACI 318 are higher for mechanical splices than for lap splices.
