Abstract:Noncontact lap splices are common in reinforced concrete construction and, although the ACI Building Code allows use of the spaced splices, design guidelines are limited. Previous experimental research on noncontact lap splices indicates a behavior similar to that of contact lap splices, but these earlier tests had small spacings of the spliced bars and were loaded under monotonic loading. No experimental tests or guidelines existed for seismic loading. The study reported in this paper provides data behavior of noncontact lap splices subjected to repeated inelastic tensile loading. The results show that spaced splices can sustain somewhat more inelastic load cycles than contact lap splices and that a truss model is an accurate description of behavior. Guidelines are proposed for the design of spaced splices.
