Rotational Stiffness of Stiffener with Different Distances to Next Stiffener

c_{θ} = \frac{E \cdot t^{3} \cdot (b_{1} + b_{2})}{4 \cdot b_{1} \cdot b_{2}}

cθ	Rotational stiffness of the buckling stiffness
E	Modulus of elasticity
t	Component thickness in the buckling panel
b₁	Distance to the next stiffener on one side
b₂	Distance to the next stiffener to the other side
