Springs due to Stiffness Semi-Rigidly Supported by Fictitious Column, Assuming Elastic Nodal Support and Considering Shear Stiffness

These formulas are used to calculate the spring constants of the stiffness using a fictitious column for a semi-rigidly supported column, taking into account the shear stiffness.

C_{u X} = \frac{X}{100} \cdot \frac{12 \cdot E I_{z}}{H^{3} \cdot (4 + k_{z})}; C_{u Y} = \frac{X}{100} \cdot \frac{12 \cdot E I_{y}}{H^{3} \cdot (4 + k_{y})}; C_{u Z} = \frac{E \cdot A}{h}

C_{φ y} = 0; C_{φ X} = 0
