Buckling of Laminated Columns

A theory is developed to determine the buckling of laminated columns composed of two or more laminations and riveted or fixed together at certain points along the column. The laminations can be of different size and material but must be long in comparison to the cross-sectional dimensions. The final result is presented in a form suitable for easy application. It is shown that for two laminations joined at an infinite number of points the problem reduces to that of a simple column. Two pinned-end columns were tested and the results are in satisfactory agreement with the theory.
