From the reference:

Example II.C-1. Truss support connection.

Given: Based on the configuration shown in Figure II.C-1-1, determine:

  1. The connection requirements between the gusset and the column
  2. The required gusset size and the weld requirements connecting the diagonal to the gusset.

The reaction on the truss end connection are:

  • RD= 16.6 kips
  • RL= 53.8 kips

Use 7/8 in. diameter ASTM A325-N or F1852-N bolts in standard holes and 70 ksi electrodes. The top chord and column are ASTM A992 material. The diagonal member, gusset plate and clip angles are ASTM A36 material.

Refer to the figure in the reference for additional details.

Results

Table 1.
Parameter RAM Connection Reference Difference
Tensile yielding of Diagonal (Interface between Gusset – Bottom right brace – Checks for gusset and brace – Yielding strength due to axial load) - Tr (kips) 173.66 174 Difference due to rounding
Tensile yielding of Diagonal (Interface between Gusset – Bottom right brace – Checks for gusset and brace – Brace side – Tensile rupture) - Tr (kips) 205.33 206 Difference due to rounding
