Title: Concrete Q&A: Evaluation and strengthening of members in existing structures
Publication: Concrete International
Appears on pages(s): 71-72
Abstract:Q. I am the licensed design professional (LDP) for a team conducting a structural evaluation of a reinforced concrete building that was completed in the mid-1960s. We’ve determined that many elements in the floor structures do not comply with requirements in the ACI 318-14 Code.1 For example, shallow beams have stirrup spacing exceeding d/2, and deep beams do not satisfy ACI 318-14 requirements for horizontal and vertical reinforcement areas and spacing. To compound these issues, the floor live load is being increased due to a change in use. Are there any ACI Code provisions that address these issues?
