If it is necessary to increase the values of several natural frequencies in a targeted manner, then this requirement can be implemented by creating an appropriate number of separate targeted constraints. The computational scheme of each of the individual targeted constraints should include racks installed at the nodes of mass application and directed along the trajectory of their movement. In some cases, individual targeted constraints can be independently installed on the original (initial) system. In most cases, on the basis of individual targeted constraints, a computational scheme of a united group targeted constraint is developed, which increases all the intended frequencies to the set values, without changing any of the other natural frequencies and not one of the natural modes. The distinctive paper is devoted verification of the proposed algorithm for the development of group targeted constraint on SCAD and “Lira Software” products.}, number={3}, journal={International Journal for Computational Civil and Structural Engineering}, author={Lyakhovich, Leonid and Akimov, Pavel and Galyautdinov, Zaur and Plyaskin, Andrey}, year={2024}, month={Sep.}, pages={186–197} }
