Has anyone come across material properties for standard LVL plies (Microllam or similar) with load applied to the wide face? Specifically I'm looking at an exterior header application in a high wind area, so some of the wall wind load will be transferred to the header. Weyerhauser has load-span tables for headers, but I'm not sure if these are applicable to all wind speeds?
I'm assuming there would be some sort of reduction in Fb and E since the wood is engineered to be loaded from a specific (i.e edgewise) direction?
And feedback is appreciated!
