description: The subject of the graduate qualification work: "Optimization of rod structures by varying the connection stiffnesses".This work is devoted to the study of optimization of rod structures by varying the stiffness of joints and frame elements. The tasks that were solved during the study are:literature analysis on the subject of research;Comparison of approaches to solve the problem of frame optimization with semi-rigid connections;Selection of the criterion for the optimal design of frame;Implementation of a program for calculating structures with various connection stiffness;Implementation of optimization algorithm;Analysis of results of frame optimizationThe problem was solved using genetic optimization algorithm. The forces in the structural elements for each variant of the frame with arbitrary connection stiffnesses have been calculated by means of the finite element method. As a target function, the function of frame metal capacity with regard for weight additions on the construction of metal structure joints has been adopted.As a result of calculations, approximated graphs of semi-rigid connection efficiency values for frames of different configurations depending on the ratio of horizontal and vertical loads have been obtained.
