The Steel Joist Institute has completely revised Technical Digest 6. This Technical Digest consists of up-to-date information regarding the effects of wind forces on steel joists. ASCE 7 is the consensus standard for determination of wind forces. Technical Digest 6 contains examples for designing K and LH Series Joists to resist upward wind forces as well as for wind force determination in accordance with ASCE 7-10. It also includes:

• Discussion of revised IBC 2012 / ASCE 7-10 Load Combinations
• Updated design examples
• Seat anchorage capacities

Chapters include:

• General Nature of Wind Loads
• Roof Design to Resist Uplift Loads
• ASCE/SEI 7-10 Wind Pressure Calculations to Determine Uplift Loading for Joists and Joist Girders
• Presentation of Uplift Design Criteria to Joist Manufacturer
• End Anchorage for Uplift Loads
• Bottom Chord Bridging for Uplift Loads
• Joist Design for Uplift
• Summary and Conclusions
