V. AISC 360-05 W Tens and Bending H3
Details
From reference (2):
Select an ASTM A992 W-shape with a 14-in. nominal depth to carry nominal forces of 29 kips from dead load and 87 kips from live load in axial tension, as well as the following nominal moments:
MxD = 32.0 kip-ft MxL = 96.0 kip-ft MyD = 11.3 kip-ft MyL = 33.8 kip-ft The unbraced length is 30 ft and the ends are pinned. Assume the connections are made with no holes.
| Result Type | Reference | STAAD.Pro | Difference | Comments |
