Question:
SHAPE‑THIN calculates a very small shear area. Why?
Answer:
The shear area is calculated as follows:
where
I-z or I-y is the second moment of area related to the axis z or y, [*S14623855*]
S-z or S-y is the first moment of area related to the axis z or y, [*S14623858*]
t* is the effective element thickness for shear transfer,
A* is the surface area based on the effective shear thickness t*.
The effective element thickness for the shear transfer t* has a significant influence on the shear area. Therefore, the defined effective element thickness for the shear transfer t* (Image 01) of the elements should be checked.
