![]() ![]() The Allowable Loads for Alternative Nailing table provides information for coiled straps when installed with different nailing schedules. Where splices are necessary in reinforcement, the length of lap splices shall be in accordance with Table R611.5.4(1) and Figure R611.5.4 (1). The Strap Lap Splices table provides the minimum splice length (Lsp) and fasteners, within the splice length, to achieve the highest allowable capacity of the strap. Vertical and horizontal wall reinforcement required by Sections R611.6 and R611.7 shall be the longest lengths practical. The Engineer/Designer of Record must evaluate and determine the adequacy of the coiled strap’s lap splice and alternative nailing applications to meet their design loads. International Residential Code 2012, R611.5.4.3: R611.5.4.3 Lap Splices.The highest allowable load given for each model is limited by the steel capacity. The lap splice, as the name suggests, is created by overlapping two lengths of rebar, then wiring them together. The length of the splice should be calculated according to the local building codes or by a local engineer and specified on the project plans. The Allowable Loads for Alternative Nailing table provides information for coiled straps when installed with different nailing schedules. Lap splicing is typically overlapping reinforcing steel over a certain length.The Strap Lap Splices table provides the minimum splice length (Lsp) and fasteners, within the splice length, to achieve the highest allowable capacity of the strap. Lap splicing of coiled straps can be used to extend standard strap lengths for designing continuous drag elements and diaphragm chord members.The cut length of the strap shall be equal to twice the “End Length” noted in the table plus the clear span dimension.For lap splice and alternative nailing information, see tables below.Fewer nails may be used reduce the allowable load as shown in the Straps and Ties General Notes. FIGURE R608.5.4 (1) LAP SPLICES For SI: 1 degree 0.0175 rad. ![]() The table shows the maximum allowable loads and the nails required to attain them. R608.5.4 Reinforcement Installation Details TABLE R608.5.4 (1) LAP SPLICE AND TENSION DEVELOPMENT LENGTHS For SI: 1 inch 25.4 mm, 1 degree 0.0175 rad, 1 pound per square inch 6.895 kPa.Refer to the applicable code for minimum nail penetration and minimum wood edge and end distances.Wood shrinkage after strap installation across horizontal wood members may cause strap to buckle outward.Use all specified fasteners see General Notes. ![]()
