Retrofitting buildings that are framed with steel joists and joist girders can present problems for the EOR, particularly if there are no construction documents available.SJI has developed two tools to assist with this process. The Joist Reinforcement Tool helps with the selection and placement of reinforcing materials on the joist needing reinforcement. The Joist Girder Analysis Tool helps the EOR determine if there is available capacity in the joist girder for any proposed new loading.
