This paper presents an efficient control strategy for magnetorheological (MR) dampers embedded in building structures to mitigate quake-induced vibrations. In this work, MR dampers are used as semi-active devices, taking the advantages of the fail-safe operation and low power requirement. By using a static hysteresis model for the MR damper, a suitable controller is proposed here for direct con...

In order to ensure the survival of building structures during earthquake periods, induced vibrations have to be mitigated. In this regard, semi-active control of smart structures using magneto-rheological dampers is becoming an emerging technology. Improvements on vibration reduction are foreshadowed when the dampers are installed at critical locations on the building structure. In this paper, ...

This thesis discusses the feasibility of structural magnetic induction dampers for dampening mechanical vibrations in buildings subjected to strong dynamic excitations. The concept of energy harvesting in various fields of engineering is first examined. Then it is applied to the design of magnetic induction dampers in buildings. Various implementations of these dampers are proposed and the rela...

Mathematical modeling and experimental research represented in this paper is aimed at dynamic force analysis of circuit cards order to eliminate or reduce stress deflection an acceptable level provide strength reliability design card assemblies subjected vibration. In conditions when viscous friction forces are negligible dampers, such as liquid cannot be used reduction oscillation amplitude cr...

After the catastrophic destruction of October 2005 Kashmir earthquake, first building code Pakistan was developed in 2007. The sole purpose (BCP) to incorporate advancements earthquake-resistant design fortify structures and ensure safety citizens against future seismic events. 2007, BCP not revised till 2021 include changes over time. However, recently updated version highlights that seismicit...

To improve the seismic performance of Chinese traditional wood-structure houses, this paper proposes to strengthen their mortise and tenon joints by applying an innovative metal damper. According dimensions “Yikeyin” houses in Tonghai area Yunnan Province, two groups six samples three types were manufactured, which one group was mounted with dampers made Q235 steels. Subsequently, a low-cycle r...
