Not necessarily, conventional earthquake-resistant high risers are designed considering the height of the structure the total height from the foundation to the roof, basically considering any underground stories as part of the structure unless for some special cases such as marine structures or high subterainean water level the lower part of the structure is ...
Your equation is correct but your calculation is wrong .
$m = 4$
$ r = 4 $
$ j = 4 $
And $ S = 4 $
There are 4 rods , 4 reactions from the supports 4 joints and 4 rotations .
S can be understood as the number Of Relative rotations at each joint .
For example at joint B there are 2 relative rotations
Take an attention to the word relative . If two ...
I think you have two questions here,
"Is there a difference in the stress concentration of a hole in an infinite thin plate loaded in biaxial tension vs biaxial compression?"
"What happens during biaxial compression?"
The first question: No, there is no difference between the biaxial and the uniaxial case. If you look at the equations, ...
Without having access to AISC 360-16, but from experience from other structural codes, I'll hazard a guess.
you can check for allowable stresses with respect to:
Also, I am not certain, the context of the word 'element', because that could include buckling, etc.
