Calculating the Critical Buckling Load for a Pinned Rectangular Wood / Timber Column

March 3, 2017 Abdul Siraj, P.E.

In this post, I will go over the third example in our mechanics of materials course covering column buckling. The goal of this example is to calculate the critical buckling load for a pinned rectangular wood / timber column.

 

The engineering problem statement states,

 

The 14 ft wooden rectangular column is pinned at both ends. Assuming that yielding does not occur, find the critical buckling load.

 

Modulus of Elasticity, E = 1600 ksi
