Question: A carpenter is checking the rebar lap splices in a foundation wall beam. The design drawings specify a Class B lap splice length for 25M bars. What is the primary function of a lap splice in rebar?
Answer options:
- To provide a decorative finish to the rebar
- To allow for future expansion and contraction of the concrete ✅ To transfer tensile or compressive stress from one rebar to an adjacent rebar
- To anchor electrical conduits within the concrete
Correct answer: To transfer tensile or compressive stress from one rebar to an adjacent rebar
Explanation: The primary function of a lap splice is to provide continuity in rebar by transferring tensile or compressive forces from one bar to another, ensuring the structural integrity of the reinforced concrete member. They do not serve decorative purposes, facilitate expansion, or anchor conduits.
