Once the pour is completed and the concrete has begun to harden (within a few hours of the pour), the wiring material has no further purpose. The lack of specific requirements for the wiring material or specification of the wire wrapping method may seem surprising at first, but the wire's sole purpose is to hold the rebar temporarily in place. The code requirements for the wiring material and fastening method are brief and note only that the wiring method employed should "secure" the rebar in place. Wiring Requirements for Lap Splicing Rebar Other types of splices that are code-compliant include mechanical splices and welded splices. Qaisar Ali CE 320 Reinforced Concrete Design-I ACI Provision for Development of Tension Reinforcement Basic Equation (ACI 25.4.2. The following are the IBC/ACI splice length requirements for the most common type of lap splice, the contact splice. ACI Provision for Development of Tension Reinforcement 9 Department of Civil Engineering, University of Engineering and Technology Peshawar, Pakistan Prof. All splice locations must be specified in the structural plans before approval. Therefore, either the IBC code sections governing concrete or ACI 318-14, current as of 2016, provide reliable information about lap splice code requirements.Ī structural engineer will take into account the standard requirements as well as exceptions for critical stress points, different splice length requirements when connecting rebar of different diameters, and requirements for staggering splices to prevent congestion at overlap points, which can result in inadequate concrete flow into the splice area. ACI code section 318-14, which governs rebar splicing, has been incorporated without meaningful modification into the corresponding concrete section of the 20 IBC. IBC code requirements are almost identical to the American Concrete Institute (ACI) codes. Although it's imperative to check your local code for detailed compliance requirements, most codes are based on the IBC ( International Building Code). In almost every construction situation, overlap lengths are subject to local building codes. Note, however, that overlap requirements vary with both rebar size and the specific structural application. From a structural point of view, the most critical aspect of a lap splice is the overlap length. The lap splice, as the name suggests, is created by overlapping two lengths of rebar, then wiring them together.
