Abstract
In this research presented modelling, computing and application particularities of the structural aseismic control device which response redaction effect an average 61-79% relatively to conventional structure under earthquake excitation. For modelling mention device reinforce solid, structural solid, spring and contact finite elements was used. For contact element accepted conventional Coulomb frictional model. Governing non linier equation of motion is modelled as multi-degree of freedom system with discontinuous and continuous models and solved adopting direct integration algorithm with coupling of the control system and system identification toolboxes. One of the very important earthquake action phenomenon-restoring force mechanism was found out, proved and it was used for modelling a novel no restoring mechanism aseismic passive control device. Investigated control device may be economically in the simple or small scale structures because have no any restoring mechanism.
