Splice bars6/11/2023 ![]() 9 (M#29) are required to be spliced using mechanical connectors. 7 (M#19 and M#22) reinforcing bars and 1.5 for No. ![]() Because the detailing requirements for these two codes can be significantly different, designers using the 2003 IBC are encouraged to compare these requirements to the corresponding 2006 IBC requirements.įor use in Equation 2, the reinforcement size factor, γ, is taken equal to 1.0 for No. For this reason, the following sections present the requirements for both the 2003 IBC and 2006 IBC for both allowable stress and strength design. As a result, the minimum lap and development lengths can vary considerably from one code to the next as well as from one design method to another. In addition, these detailing requirements have been frequently revised in recent years. The required length of lap or development is determined according to the design procedure used and type of detail employed. Reinforcing bars may be spliced by lapping the reinforcement, by proprietary mechanical splices or by welding. The development of the reinforcing bars relies on mechanical interlock of the bar deformations, hook, and/or anchor along with sufficient masonry cover to prevent splitting of the masonry. Reinforcement can be developed by embedment length, hook, or mechanical anchoring device. Splicing of reinforcement serves a similar purpose to adequately transfer stresses from one reinforcing bar to another. ![]() Minimum development lengths are necessary to adequately transfer stresses between reinforcement and the grout or mortar in which it is embedded.
