Springs due to Stiffness Restrained by Fictitious Column, Assuming Elastic Surface Foundation and Considering Shear Stiffness

The formulas shown here result in the spring constants of the support conditions of the "Stiffness via Fictitious Column Response" function for a restrained column, taking into account the shear stiffness.

C_{u X} = \frac{12 \cdot E I_{Z}}{H^{3} \cdot A_{h e a d} \cdot (1 + k_{z})}; C_{u Y} = \frac{12 \cdot E I_{Y}}{H^{3} \cdot A_{h e a d} \cdot (1 + k_{y})}; C_{u Z} = \frac{E \cdot A}{h \cdot A_{h e a d}}

C_{φ y} = \frac{E \cdot I_{z}}{A_{h e a d} \cdot h} \cdot \frac{3}{1 + k_{z}}; C_{φ X} = \frac{E \cdot I y}{A_{h e a d} \cdot h} \cdot \frac{3}{1 + k_{y}}
