Spring Constants – Semi-Rigid Column Head, Restrained Column Base, Elastic Nodal Support, Neglecting Shear Stiffness

These formulas are used to calculate the spring constants of the stiffness of an elastic nodal support. In this case, a column with a semi-rigid column head and a restrained column base is considered on the basis of modeling with a fictitious column, without considering the shear stiffness.

C_{u, X} = \frac{12 \cdot E I_{z}}{h^{3}}

C_{u, Y} = \frac{12 \cdot E I_{y}}{h^{3}}

C_{u, Z} = \frac{E A}{h}

C_{φ, X} = \frac{4 \cdot E I_{y}}{h}

C_{φ, Y} = \frac{4 \cdot E I_{z}}{h}
