I am currently building a house and need to modify a glu lam beam. I have a simple span of 16 feet over a garage opening. The beam supports only the roof trusses/roof. The support consists of 2 glu lam beams, each measuring 19 inches deep and about 5 inches wide. I need to cut the bottom 5 to six inches out of the beam.

I am looking for advice and calculation software or tables to make sure I can handle the loads.

Suggestions?

Boise Cascade just replied to my e-mail. He said if you reduce the size it is conservative to analyze it as if it were D-F #2. So analyzing it as if it were (2)6x14 is good enough.
