ASCE 7-05 Specified Wind Loads• It all looks simple when the building structureappears to be a simple rectangle made up oflarge monolithic elements as described inFigure 6-3.• The reality is when the building shape is morecomplex comprised of numerous elements thenit is not as easy to determine the loadings onjoists in corners and Joist Girders that passthrough both edge and corner zones.SEAoT State Conference November 6-8, 2008 Houston TX SEAoT - 28
