This online axial Euler buckling solverwill determine the Euler buckling load for an axial member with

up to 5 segments each with its own elastic modulus and area moment of inertia. Boundary conditions

of free, simple support, fixed slope and or elastic spring can be applied at the start and end of each

segment. The output includes the buckling load, maximum compression stress using the smallest

input area and a slenderness ratio using the full length and smallest EA value. The later two output

parameters can be used to determine if Euler buckling is an adequate representation of the

simulation. Compression stress values approaching the material yield and low slenderness ratios

suggest nonlinear buckling maybe more appropriate.

The calculator matches the classic Euler buckling equation Pcr = EI(π/KL)2 for simple-simple (K=1),

fixed-fixed (K=0.5), simple-fixed (K=0.7) and fixed-free (K=2) end conditions.
