4 Bolts Stiffened End Plate Connection per AISC 358-16 & AISC 360-16

How does ideCAD design four bolts stiffened end plate connection according to AISC 358-16 & AISC 360-16?

L_h = distance between plastic hinge locations, in. (mm)
L_st = length of stiffener, as shown in Figure 6.5, in. (mm)
M_pr = probable maximum moment at the plastic hinge, kip-in. (N-mm), given by Equation 2.4-1
S_h = distance from the face of the column to the plastic hinge, in. (mm)
V_gravity = beam shear force resulting from 1.2D + f1L + 0.2S (where f1 is a load factor determined by the applicable building code for live loads, but not less than 0.5), kips (N)
V_u = shear force at the end of the beam, kips (N)
b_bf = width of beam flange, in. (mm)
d = depth of connecting beam, in. (mm)
t_p = thickness of end-plate, in. (mm)

Four bolt end-plate connections consist of welding the beam to an end plate and bolting the end plate to a column flange.

Connection Design Parameters

Resistance factor for ductile limit state (Yielding Limit State):

Resistance factor for Non-ductile limit state (Rupture Limit State): 

Distance from the face of the column to the plastic hinge, S_h, for four bolts stiffened end plate connection, is the L_st + t_p

The probable maximum moment at the plastic hinge is given below, according to AISC 358-16.

The moment at the face of the column, M_f., is calculated according to AISC 358-16 Eq. 6.8-1 given below.

The V_u used in the dimensioning of the joint is determined according to the equation in the above image by summing the shear force determined based on the yield state and the shear force calculated from the combination of 1.2G + 0.5Q + 0.2S on the plastic joint at the end of the beam.
