The load distrivution factor in the perforated square plate under concentrated loads acting at arbitray points through elastic media are calculated for more accurate analysis of the plate. In the calculation of the load distribution factor, the perforated plate was converted into an orthotropic plate using the method suggested by J.B.Mahoney. The ortohtropic auxiliary plate extened in the both directions of the real plate was considered to get the deflection of the real plate by superposition method. The angle support of the real plate at four corners was replaced by point supports with equivalent elastic stiffness in the auxiliary plate. The deflections of the real plate obtained from the superposition method were compared with the results from ANSYS code to show the validity of the current method, then the calculation for the load distribution factor was performed.
The results shows that the load distribution factor at periphery of the plate is larger than that of the central location with the variation of the stiffness of elastic media. This load distribution factor could be used for re-distribution of the loads in more accurate analysis of the plate loaded through elastic media, as well as it can be used for the anlysis of the elastic media as the load factors.
