The paper investigates the dynamic behavior of structural systems obtained by connecting a moment-resisting frame structure with vertical rigid truss pinned at base, known in literature as “strongback,” and equipped added fluid-viscous dampers. strongback, designed order to remain elastic field under strong seismic ground motion, acts mast imposing linear lateral deformed shape. By regularizing...

Semi-active control devices have received significant attention in recent years because they offer the adaptability of active control devices without requiring the associated large power sources. Magnetorheological (MR) dampers are semi-active control devices that use MR fluids to produce controllable dampers. They potentially offer highly reliable operation and can be viewed as fail-safe in th...

In this paper, the development of non-linear building isolation systems is overviewed. The study summarizes commonly used linear in two categories, which are base and inter-storey systems. Typical isolators including Lead-Rubber Bearings Friction Pendulum viscous damper Tuned Mass Damper reviewed. analysis design also reported. After that, introduced from aspects based on their dynamic characte...

Equivalent linearization is an available method widely used to conveniently predict the nonlinear responses of buildings. The present study proposes a seismic response prediction based on equivalent stud-type viscoelastic dampers with amplitude dependencies for that there not lot research discussing estimation such dampers. Through analyses, authors found proposed leads structural design proces...

Conventional control of household refrigerators is typically accomplished with simple, single-sensor control systems. Though cost-effective this approach allows temperature dependencies to exist between compartments, producing non-optimal energy consumption. In order to study the performance of the conventional refrigerator a computer model was developed. Analytical results were generated to de...

To reduce the damages of aeolian vibration of conductors to the power transmission networks, the most common method is installation of Stock-bridge dampers. Estimation of the damper’s dissipated energy is an important factor in determining the number and location of installation of these types of vibration absorbers. This estimation is strongly dependent upon the assumed mode shape of the condu...
