Nowadays, there is a spread use of plates for various purposes because of their good performance and economic advantages. Hence, it seems that it is necessary to investigation the plate behavior. In this study buckling behavior of long plates under the combination of bending, shear and axial loads are studied using the finite element method. The effect of boundary conditions of the long plate under the combination of loads is considered. The effects of adding holes to the long plates are also considered. The holes have various radii with a unique array. The behavior of load intersection in non-pierced and pierced plates is compared. The loading consists of bending, axial and shear which all of them are in-plane and are applied to the plates’ edges. For this purpose, more than 1000 models were created. For the investigation, two of the loads are applied to the plate and the load bearing capacity of the third load is calculated. Results showed that long plates under axial load have less sensitivity to holes in comparison with the shear and the bending loads. The holes with diameters equal to or less than 0.06 of plate’s width can hardly influence the buckling behavior.
