I am trying to check the effects of combined bending of an aluminum member that will be subjected to axial loads per Section 3.4.7 of the Aluminum Design Manual. My S1*< Lambda < S2*. The member I am checking is 14' long. Phi * FL (allowable compressive stress) is coming out as a negative...
Thanks - eliminating AASHTO 3.24.3.2 from my calcs helped bring everything down to where it should be.
One other question:
Does the 640 pound/ft lane load apply to all truck loadings (H15, Type 3, HS-20, 25, 27, etc.) or is it only applied for HL 93 loading?
Thanks
When computing live load maximum moments on an interior or exterior beam due to standard loading (H15, HS 20, etc.), are the axle loads and wheel loads to be distributed per AASHTO 3.24.3.2 (E = 4 + 0.06 S, where S = Span Length)? My rating factors are coming out way high (4+), when I know they...
