[arefinmahadi]

Dear All,

By the side i have also attached the section where the boxed are left blank for the cases mentioned above. Can u please help me understand why. Or where it is referenced.

Thanks

If you read through the commentary before the table, you will see that they limit the plate thickness, t, to db/2 + 1/16" for a single row of bolts to ensure that the plate moment strength does not exceed the moment strength of the bolt group in shear. If you get to that thickness, there's no reason to use a thicker plate as the bolts will fail first anyway so you are wasting steel.

Now i get it. It would be great help if u could specify the where to look at in Commentary. I went through Chapter J but could not find the part where it is discussed.

Thanks in Advance.
