Properly Specifying Steel Joists


Open web steel joists are an efficient, economical method of framing building floors and roofs, but there are some basics that should be covered in the structural design and specifying process. This presentation will highlight the current codes and specifications that apply to steel joist construction and provide insight into the best way to plan your next project. Practical guidance will be provided to both avoid unnecessary RFI’s and to maximize system economy.

Learning Objectives of Webinar

  • Proper use of reference standards
  • Avoiding common pit-falls and unnecessary RFI’s
  • Tips for economy with the specified steel joist system
  • Awareness of design tools available from the Steel Joist Institute
