There are conditions that must be met in order to be used in 3 types of frames with special moment frames or intermediate moment frames. These conditions are given in AISC 358-16 6.3. ideCAD Structural automatically checks and reports these conditions.

Plastic hinges cause inelastic bending deformations in the joining beam and column panel area in the joints with end plate. Therefore, stronger column, stronger joint and acceptible weak beam design are considered as philosophy. For this reason, the length of the plastic hinge and its distance from the column flange are especially checked in the table below.

...

Also, it should be checked that:

1. The clear span-to-depth ratio of the beam is limited:
   (a) For SMF systems, 7 or greater.
   (b) For IMF systems, 5 or greater.

2. The protected zone is determined:
   (a) For unstiffened extended end-plate connections: the portion of beam between the face of the column and a distance equal to the depth of the beam or three times the width of the beam flange from the face of the column, whichever is less.
   (b) For stiffened extended end-plate connections: the portion of beam between the face of the column and a distance equal to the location of the end of the stiffener plus one-half the depth of the beam or three times the width of the beam flange, whichever is less.

3. The end-plate should be connected to the flange of the column.

4. Rolled shape column depth is limited to W36 (W920) maximum. The depth of built-up wide-flange columns is not exceed that for rolled shapes.
