In this paper, a technology enabling to optimize the topology of truss or frame structures with genetic algo-rithms is presented. The objective function is total mass of the structure elements. Constrains consist of equilibrium equations and conditions on stresses in the elements: stresses cannot exceed allowable value and must be above some threshold value. The values of the objective function are calculated with package ANSYS. Genetic algorithm with interface is implemented in C++. Exchange of data between ANSYS and C++ goes through temporary files. Numerical examples are presented.
