Evaluation and modification of joists may be required for many reasons: building renovations, field deviations, additional loads, and more. SJI’s Technical Digest No. 12 addresses how to evaluate existing joists and Joist Girders for changes to the original loads and then how to modify the joists and Joist Girders to adequately carry the required loading. This SEU session reviewed information from the technical digest, with examples of joists needing to be retrofitted. The discussion then moved to methods and examples of evaluating existing open web steel joists and Joist Girders for revised loading conditions. Finally, common options were presented for modifying these joists and Joist Girders.
Session Length: 1.5 Hours
