Annotation: The article suggests a method of specifying a set of variants of bar structures for structural and parametric optimization problems of geometry, cross sections of bars and structure topology. The method includes formation of tuples of nodes for describing set of topology variants of bar system and using of discrete design variables to select specific topology variants during the optimization process. In this case topology variants can be formed with different number of nodes and bars and on the stage of the data input of optimization problem. The structural and parametric optimization problem is formulated for eaves truss. The article gives the instance of the specifying of tuples with the nodes for eaves truss. It is described the implementation of the proposed method in program for optimal design of steel structures OptCAD. Structure optimization problem is solved by harmony search method.
Keywords: bar structures, steel structures, topology optimization, discrete design variables.
