in the present paper axial distributions of plasma and floating potentials, electron and iondensities and eedf have been measured in the dl region of a hg discharge constriction. an attempt hasbeen made for the resolution of opposing charged layer structures in dl. excitation processes in theconstriction region are studied. using the linearization method for the nonstationary balance equationss...

An innovative lateral force resisting system is investigated that allows steel braced frames to uplift and rock on their foundation, partially isolating the frame. Passive energy dissipation devices are implemented at the uplifting location to control the rocking response to within allowable limits. The structure’s gravitational forces provide an inherent restoring force during the rocking resp...

The present study focuses on the estimation of response building structure supplemented with superelastic shape memory alloy (SMA) damper under stochastic seismic excitation. To this end, has been determined using linearization method random earthquakes and control efficiency SMA is compared yield damper. As output, top floor root mean square (rms) acceleration displacement are presented here i...

Abstract Analysis of the dynamic response a complex nonlinear system is always difficult problem. By using Volterra functional series to describe system, its analysis can be similar Fourier/Laplace transform and linear transfer function method analyse system's response. In this paper, for systems based on developed. Firstly, recursive formula least square established solve kernel vector, corres...

One of the effective methods for ensuring seismic resistance buildings and structures located in seismic-prone areas is use an active protection system. The most common at present system based on isolation. Seismic isolations form rubber-metal (RMB) pendulum sliding bearings (PSB) have gained great popularity our country abroad. Also known isolation a belt foundation level. Unlike RMB PSB, easi...
