From the reference:
Determine the adequacy of the KT connection shown in the figure below. The noding eccentricity is -1.08 in. Branch 3 has a 100% overlap with branches 1 and 2.
Refer to the figure in the reference for additional details.
Results
| Parameter | RAM Connection | Reference | Difference |
|---|---|---|---|
| Overlapped – Local yielding of branch due an uneven load distribution (kips) | 167.12 | 170.5 | 2%1 |
| Overlapping – Local yielding of branch due an uneven load distribution (kips) | 167.12 | 133 | 26%1 |
Note: (1) The example considers 100% overlap for branch 3, but it has around 65%, which leads to a different capacity value.
