Introduction:

The load at which the column just buckles (or bends) is called crippling load.

 

Description:

 

  • The load at which the column just buckles (or bends) is called crippling load. Consider a column AB of length l and uniform cross-sectional area, hinged at both of its ends A and B.
  • Let P be the crippling load at which the column has just buckled. Due to the crippling load, the column wiII deflect into a curved form ACB as shown in Fig.

 

Where C1 and C2 are the constants of integration and the values are obtained as follows:

At A, x = 0 and y = 0

As if C1 = 0, then if C2 is also equals to zero, then from Eqn no. (i), we will find that y = 0. This means that the bending of the column will be zero or the column will not bend at all, which is not true.

 

Taking the least practical value.
