What are all the stress components in this chimney

What are all the stress components in this
chimney? For masonry, what stress is important?

• Already talked about multiple stresses at a
  point
• Beams get both shear stress and normal stress
• Pressure vessels get two normal stresses

• Now look at stresses at a point due to combined
  loading. Procedure
• Must decide where the critical point is (i.e.
  where does maximum stress occur?)
• Cut the member at that point and solve for
  internal forces
• Determine stresses from these internal forces
• Add like stresses, i.e.
• stotal s1 s2 s3 ...
• ttotal t1 t2 t3
• Summarize these stresses on a stress element
  called alligned stress element or initial stress
  element.

1. Decide what point to look at
2. Section and solve for internal forces
4
3. Solve for stresses add like stresses
4. Summarize stresses on an initial stress
element
5
Where would you analyze these structures if
interested in max stress?
