Abstract

Incorporation of friction devices in structures is an innovative method for nontraditional seismic protection, aiming at to avoid or to minimize the inelastic deformations in the main bearing elements. Paper deals with the modeling of friction forces with decreasing friction coefficient during the sliding phase and its influence to the seismic response of structures with friction devices. Numerical simulations of the seismic response of a four story frame with friction devices are carried out by use of the velocity model of friction forces. The influence of the decrease of the friction coefficient with the growth of the relative velocity of sliding surfaces to the maximum displacements of the floor slabs, maximum story drifts and maximum relative displacements of the sliding surfaces is studied. Conclusions are drown and design recommendations are given.
