Abstract
The present paper is conceived so as to give a general image of the problems concerning the passive response-control structures. An attempt to organize the different aspects of the passive control of seismic structural vibrations in a rational way is made. Choice of optimal bracing system was tested on 10-storey administrative building steel frame structure in nuclear power plants. Dynamic and strength characteristic classical bracing system in form V and X and system with TPEA devices are presented. Analytical stress-strain relation for refined plasticity model and stiffness matrix for TPEA devices are presented in good agreement with experimental results. The element COMBIN39 from ANSYS library using to nonlinear model is very effective. Bracing system with TPEA device show that the energy-dissipation capacity of the structure increases and then the seismic effects are maximal reduced using it.
