@ JAE, I am aware that current AISC has different equations I rather to use the old equation since it looks much simpler to me than new equations. I think I should be fine using the old one as new AISC states "User Note: Section H2 is permitted to be used in lieu of the provisions of this...
Thanks everyone for sharing your thoughts, below is a snapshot of what I have. the shear stress is very small almost 20% of its allowable (I know if the shear stress is less than 60% of shear allowable stress then it can be ignored). so basically I have strong axis bending moment, weak axis...
@ JAE, Von Mises criterion is about three principal stresses i.e max normal stress, minimum normal stress and shear stress, right? here I have one tensile stress, one strong axis bending stress but the third one is weak axis bending stress and they all produced by one single load, do you believe...
so there is no need to simply add strong and weak axis bending stresses (or do a vector summation) and check that too? I should be checking it as below:
1) fbx < Fbx
2) fby < Fby
3) fa < Ft
4) fa/ Ft + fbx/Fbx + fby/Fby ≤ 1.0
Thanks
Thanks for replies:
yes the three stresses are imposed at the same time but there is only one load applied on the plate. (load has lateral angle so produces weak axis bending too)
I am checking stresses per AISC 9th edition chapter H, combined stresses, (H2. AXIAL TENSION AND BENDING) and...
Hello everyone,
I am checking stresses on a rectangular plate (SA-516-70) results from an external load. below is a summary of what I have:
1) Maximum strong axis bending stress is fbx = 15,964 psi, allowable strong axis bending stress= Fbx =0.6 x Fy = 22,800 psi.
2) maximum weak axis bending...
