Abstract Nowadays, retrofitting-damaged buildings is an important challenge for engineers. Finding the optimal placement of Viscous Dampers (VDs) between adjacent structures prone to earthquake-induced pounding can help designers implement VDs with optimizing cost construction and achieving higher performance levels both structures. In this research, linear nonlinear 3-story, 5-story, 9-story S...

When a spacecraft lands, a large shock load can lead to undesirable responses such as rebound and tripping. The authors previously discussed the problem of controlling these shock responses using momentum exchange impact dampers. An active/passive hybrid momentum exchange impact damper, which included an active actuator, was proposed. Themomentum exchange impact dampers’ performances are evalua...

additional dampers are employed in order to decrease the dynamic response of structure against the earthquake and wind loading recently. in this study, two types of systems related to waste of inactive energy, i.e. frictional damper which is categorized in dampers dependent on movement and viscoelastic damper which is categorized in dampers dependent on velocity, in making steel structures resi...

In recent years, destructive earthquakes have shown the deficiencies of the existing buildings. One of the most effective mechanisms for dissipating the earthquake energy is inelastic deformation of the steel components. The objective of this research is to study the application of metallic dampers for dissipation of the earthquake energy and to investigate the behavior of concrete structures i...

The traveling wave and slope amplification effects should be considered in the shaking table test of large-span structures mountain areas. Based on structural characteristics site conditions a structure area, this paper designed high-rise steel frame with viscous dampers through finite element analysis to amplify seismic waves time delay. Then, original models similarity ratio 1/40 were made fo...

The damped outrigger system is in widespread use as a damping modification for tall buildings that provides high additional addition to the bending back effect against core. However, while enhanced seismic performance of systems was confirmed previous studies all over world, general-purpose optimal design method focusing on modal ratios has not been established yet. This paper proposes an dampe...
