Where can put contraction in building lenght ?

Quote: "Contraction or isolation joints shall be provided to divide structural plain concrete members into flexurally discontinuous elements in accordance with ACI 318 Section 22.3"

1. What about limits of the building in the plane in IBC ?
2. Where can find ACI 318 ?

If I understood your question, Contraction joint may be provided depending upon temperature condition in the site. If the site is at hot zone, it is suggested to provide contraction of expansion joint within 25m of the buildig length.
