Subject: Beam properties

 

I have an existing building with RTU’s being added and need to analyze the beams. The simplest of course is a table of properties. The beam dimensions don’t fit W, M, S, or HP per AISC 9^th. It is an I-shape with a slightly tapered flange (I didn’t get that difference in thickness dimension), d=12-3/16”, bf=5”, tf=3/8” (by subtraction) and tw=1/4”. The beams are fairly light. Does anybody know where to find the properties for these? They are in a 50 to 80 year old Denver, CO building.
