Cambering Can Be Problematic“It is easy to just bend the shape a little”But if there are holes in flanges, fracturemay take placeSpecify that holes should be madeAFTER cambering
CONNECTIONS• Major influence on constructioneconomy: 50 % and more of a projectframing cost is tied to connections• Connections influence member responseand frame response• Analysis with suitable connectionproperties can be very complex – but isneeded and now required by many codes• Consequently, there is a very largenumber of current studies of connectionbehavior and strength
