Cold-Formed Steel Reinforcement for Improperly Cut Wood Composite I-Joists

摘要: Wood composite I-joists have become an attractive option for floor joists in residential construction. One disadvantage of is the restrictions on hole size and inability to notch top compression flange. This technical paper evaluates two cold-formed steel reinforcers strengthen that been improperly cut—one reinforce flange, another web. The were tested at various locations along length beam. Based upon testing results, notched with flange retained 60.2% strength 77.0% stiffness original I-joists. web single-sided 78.2%% 95.7% double-sided I-joist 95.1% I-joist. These reductions can be used determine if reinforce...
