The subject of transverse spacing between two reinforcing bars lapped in a noncontact or spaced tension splice is addressed in the ACI Building Code (ACI 318-89). The code provisions are based on monotonic tests performed before 1957 of pullout specimens, beam-end specimens, and small-scale beam specimens, where the clear splice-bar spacing was small (less than 3 d b or 50 mm). Tests reported in 1991 of full-scale flat plate specimens subjected to monotonic and repeated inelastic loading in direct tension did not check splice-bar spacings beyond the ACI Code limit of one-fifth of the required lap length. The study reported in this paper provides data on 17 full-scale slab specimens, each reinforced with three lap splices, loaded in flexure, and designed to fail in a splitting mode. Splice-bar spacings below and above the ACI limit were checked. The objective was to check the validity of the ACI provisions based on the results of this study and other studies of noncontact lap splices.
