Joist and Joist Girder Reinforcement Tool

This design tool has been developed by the Steel Joist Institute to assist the SER and the steel fabricator with the complex task of reinforcing open web steel joists and Joist Girders in order to increase their strength to accommodate added loads for which they were not originally designed. Seventeen individual spreadsheets are available for reinforcing schemes.

Joist and Joist Girder Reinforcement Tool version 3.0 is available for free download. Complete the form or log in to your account to access this tool. SJI may notify you when updates are made to this design tool.

Webinar On Demand:
Joist and Joist Girder Reinforcement

Joists and joist girders often require reinforcement when considering loads not included in the original design. Provided in this webinar is a discussion of the types of reinforcement that can be used. A description is given for an SJI tool that determines if reinforcement is required and designs the reinforcement for chords and webs. An example of reinforcing a joist girder using the tool is also provided.

Technical Digest 12
Evaluation and Modification of Open Web Steel Joists and Joist Girders

The Steel Joist Institute’s third edition of Technical Digest 12 gives the reader information regarding the application and usage of steel joists and joist girders. Technical Digest 12 covers the evaluation of existing steel joists and joist girders to carry additional loads not accounted for in their original design. Technical Digest 12 also addresses situations where the configuration and/or the original geometry of the steel joists or joist girders need to be modified in the field.

Joist Girder Analysis Tool

Design Tool

This Joist Girder Analysis Tool assists the SER in determining the strength of each member within existing joist girders. The tool is applicable for G or VG type joist girders, which may be symmetrical or unsymmetrical at the ends. If strengthening of some members is required, it is suggested that the Joist and Joist Girder Reinforcement Tool be downloaded to assist in designing required reinforcement.
