I am trying to figure out how to calculate how to calculate the moment of inertia of a bolt group. In accordance with page 7-9 or AISC 13th edition Ip=Ix+Iy in units of in4/in2
Are you suppose to include the bolt area in the calculation of Ix and Iy? The way the units are written (in4/in2) I wouldn't thinks so, but then again, if you don't, you are not truly getting Ix or Iy of the bolt group.
