According to California Building Code requirements for retaining walls, what is the minimum lap splice length for #6 reinforcing bars in normal weight concrete with f'c = 3000 psi in tension?
Correct Answer
A) 30 inches
Per CBC Section 1909.6.2.2, the development length for #6 bars in 3000 psi concrete is approximately 25 inches, and lap splices in tension require 1.3 times the development length per Section 1909.6.2.5, resulting in approximately 30 inches minimum lap length for proper load transfer.
