Euler's buckling formula.

Parameters:

• P = Force [N] = Allowable compression force on the column
• E = Young’s Modulus [Pa] or [N/m²] = material properties
• I = Moment of Inertia [m⁴] = shape properties
• K = Constant, depending on boundary conditions
• L = Length [m]

Data:

• Euler has presented around 1759 the basics of the buckling formula for columns.
• In many engineering fields this formula is used to calculate the safety on collapsing by buckling of column type girders. Because it concerns individual items of a structure and not the integrated structure, it is used to calculate each member individually. So it is probably not easy to design a Slide Chart to covers many girders.

Question:

1. Do you know Slide Charts for calculating Euler’s allowable force for specific columns of different shape and materials as steel, concrete, timber, aluminium, etc.
