Details
From the reference:
Example 2.0 - COMPRESSION – In this example, a diagonal cut is added to the gusset plate in Figure 11 as shown in Figure 12. The simplified design method is used to calculate the strength. The gusset plate is 3/8 in. thick of A572 Grade 50 material. The LFRD and ASD loads are 60.0 kips tension/35.0 kips compression and 40.0 kips tension/23.3 compression, respectively.
Refer to the figure in the reference for additional details.
Results
| Parameter | RAM Connection | Reference | Difference |
|---|---|---|---|
| COMPRESSION - Flexural strength of Leg 1 (kip·in) | 252.37 | 256 | None (Difference due to rounding) |
| COMPRESSION -Shear yielding of Leg 1 (kips) | 112.5 | 113 | None |
| COMPRESSION -Flexural strength of Leg 2 (kip·in) | 300.44 | 827 | Difference due to the program takes the gusset leg depth in the border of the plate in the beam connection |
| COMPRESSION -Shear yielding of Leg 2 (kips) | 112.5 | 132 | Difference due to the program takes the gusset leg depth in the border of the plate in the beam connection |
