channel lintel sizes
i'm wondering if their is a table or info available on sizes of a steel channel to be used as a lintel for a reinforced wall opening of 12'.
i doubt it except for ones made by folks in-house.
i just figure out ireq to give l/600 or less deflection for a triangular or rectangular chunk of masonry, usually a 4-minute calculation.
