In order to minimize the central deflection of a stiffened plate under different static loads,rib layout optimization of the plate was studied based on a meshfree formulation incorporating the constrained random direction method. Because the rib position needed to be changed from time to time during the optimization process,in the proposed method,a series of nodes were used to discretize the structure; and the nodes did not need to be redistributed when the rib position changed. The deflection of the stiffened plate was calculated by the meshfree formulation,and the rib layout of the plate was optimized by the constrained random direction method. The validity of the proposed method was verified by several examples.
