Yuying,

The maximum spacing for lap splice applications is defined in ACI 318-14 Section 25.5.1.3, which states:
"For noncontact splices in flexural members, the transverse center-to-center spacing of spliced bars shall not exceed the lesser of one-fifth the required lap splice length and 6 in."

Let us know if you have any additional questions.

Regards,

Bryan
