Technical Digest 6 Design of Steel Joist Roofs to Resist Uplift Loads

Description

The Steel Joist Institute has completely revised Technical Digest 6. The Technical Digest consist of 49 pages 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
