shear calculation
i am trying to do a design for a hss 6x6x0.25" (structural tubing)that will be located between 2 storefront (10'x10' each) and attached to a 12"x17" concrete column but unfortanely i don't have still the steel manual. can anyone please tell me the shear factor or the allowable shear for it. thank you in advance.

72.5k - factored
48.3k - service
structuraleit, my beam has a fy= 36000 ksi, and is an astm a36 steel, beleive that i should consider my allowable shear stress like 040 fy. what do you seen? the values that you gave me look like a little high, no offense.
well, you said hss, hss (rectangular) is typically only available with 46ksi yield (a500 gr. b) - i believe there would be a significant up-charge to get a36 hss.  additionally, per the shear provisions in aisc, you use 0.6fy.  using fy=36ksi, the values drop to :
56.7k - factored
37.8k - service
structuraleit, thank you for you rteply.

mayito, 0.6fy is the nominal shear stress.  for asd, this becomes 0.6fy/1.67 = 0.359fy for hss members.
it is 0.4fy for webs of rolled i-shapes, where omega is 1.5.
