Appears on pages(s): 63-64
Keywords: slab-on-ground, welded wire reinforcement, crack, requirements
Minimum lap splice lengths for welded wire reinforcement (WWR) are presented in Section 25.5.4 of ACI 318-19 and Section 18.104.22.168(a) of ACI 301-20. In this Q&A, these requirements are interpreted for slabs-on-ground that are not included as part of a building’s lateral force-resisting system. In addition, the Q&A discusses crack control recommendations for slabs-on-ground per ACI 360R-10.
