The results are generated with SDC Verifier 3.7.1 and calculated with FEMAP v11.0.0. The example was calculated in American unit system.
Note: Maximum deflection and beam selection has not implemented yet in SDC Verifier.
Task: Select a square ASTM A500 Grade B HSS beam to span 7.5 ft. The loads are a uniform dead load of 0.145 kip/ft and a uniform live load of 0.435 kip/ft. Limit the live load deflection to L/240. The beam is continuously braced.
From AISC Manual Table 2-4, the material properties are as follows:
ASTM A500 Grade B
Fy = 46 ksi
Fu = 58 ksi
From Chapter 2 of ASCE/SEI 7, the required flexural strength is:
Minimum Required Moment of inertia
Determine the minimum required I as follows.
Select an HSS with a minimum lx of 2.85 in4.,using AISC Manual Table 1-12, and having adequate available strength, using AISC Manual Table 3-13.
Try an HSS 3½×?.
From AISC Manual Table 1-12, lx = 2.90 in4 > 2.85 in4o.k.
From AISC Manual Table 3-13, the available flexural strength is:
Units which were used in calculation:
1 kip = 1000 lb
1 ft = 12 in
1 ksi = 1000 psi (lb/in^2)
