This webinar will have three parts. Firstly we will discuss and show examples of joists needing to be retrofitted. Secondly, we will demonstrate methods to evaluate existing open web steel joists and Joist Girders for revised loading conditions. The last part will demonstrate the methods with examples of how to modify existing open web joists. This webinar parallels the Steel Joist Institute publication, Technical Digest No. 12 “Evaluation and Modification of Open Web Steel Joists and Joist Girders.
This in-depth webinar is sponsored by the Steel Joist Institute (SJI) and participation will earn you 1.5 PDHs.
