Spring Constants of Stiffness Using Fictitious Supports, Assuming Elastic Surface Foundation for Restrained Column and Neglecting Shear Stiffness

These formulas are used to calculate the spring constants of the stiffness using fictitious columns, assuming an elastic surface foundation for restrained columns while neglecting shear stiffness.

C_{u X} = \frac{12 \cdot E I_{Z}}{H^{3} \cdot A_{h e a d}}; C_{u Y} = \frac{12 \cdot E I_{Y}}{H^{3} \cdot A_{h e a d}}; C_{u Z} = \frac{E \cdot A}{h \cdot A_{h e a d}}

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