Technical Digest No. 11, the latest in the Steel Joist Institute’s series of publications, illustrates procedures for the structural engineer to properly analyze, design and specify open web steel joist and Joist Girder moment frames to resist wind and seismic lateral loads. The design methodology provided is limited to single-story structures subjected to wind and seismic loads; however, the design procedures are applicable to multi-story moment frames subjected to wind loads.
This 120-page second edition, written by James M. Fisher, Ph.D., P.E., Perry S. Green, Ph.D., and Joseph J. Pote, P.E., is an extensive update of the previously issued Technical Digest No. 11 on joist and Joist Girder moment frames. The digest covers the importance of the relationship between the specifying professional and the joist manufacturer, describes the analysis requirements for modeling the moment frame and provides design methodology for lateral wind loads and seismic loads. It also shows how to properly design and detail the connections and lateral bracing. There is an extensive discussion on the specification of loads and other design requirements that the specifying professional needs to provide to the joist manufacturer. Two detailed design examples are contained in the digest.
