Spring Constants – Hinged Column Head, Semi-Rigid Column Base, Elastic Nodal Support, 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, considering 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 A}{h}

C_{φ Y} = 0

C_{φ X} = 0
