AISC Design Guide 11 - Floor Vibration - Estimating Moment of Inertia of Joist Chords
(OP)
Referring to Design Guide 11, calculating the effective moment of inertia of open web joists - AISC equations use the moment of inertia of the chords (only) of the joist. My question - How are you supposed to know the area of the chords and distance to their centroid when in the design stage (i.e. how am I suppose to know the area, centroid or moment of inertia of the chords in a 30K8)?
Thanks!
Thanks!

I should be able to use that then with the depth of joist in order to solve the rest of the problem.
Thanks.
