In the bolt shear design check for slip critical bolts using 1 1/4" A325 SC (Class A), the minimum bolt pretension is taken as 81 kips when it should read 71 kips as per AISC table J3.1. Model along with snap shots attached. SC bolts defect.zip

In Single plate connection to HSS, while checking punching shear on the HSS column support, RAM takes the lp (length of connection) as the width of the shear plate instead of the length. Please advise. Snapshots are attached for easy reference.

In truss connection of HSS (chord and branch), in the interaction equation (last check) it uses the maximum ratios from each case of loading, when in interaction equation we should use each maximum ratio with its corresponding ratio. Attached a model…

In Knife plate connection, in checking brace tension rupture, and while calculating the "U" (Shear lag Coefficient) the "l" of table D3.1 is taken as the spacing between the bolts when it should be taken as the length of the connection that's to say the…
