This paper provides the results of the investigation on the optimum topology of the deep beam structures subjected to the self-weight. As the objective function in the optimization process, the strain energy to be minimized is employed and the initial volume of structures is adopted as the constraint function. The resizing algorithm devised from the optimality criteria method is used to update the hole size of the cell existing in each finite element. Several important topology
optimization parameters are throughly tested for case of distributed load such as the self-weight. Various essential boundary conditions are also employed to provide the information on the effect of the essential boundary condition to the final optimum topology of deep beam structures. The filtering process for avoiding the checker boarding phenomenon is also consistently used. From numerical tests, the optimum topology of the deep beam structures subjected to the
self-weight is closely related with the values of optimization parameters and the filtering process play important role in order to find the proper optimum topology of the deep beam structures.
