A Review Study on Composite +8 Structure with Application of Damper on Different Locations Using Time History Analysis

Abstract

These viscous dampers are unique in that the velocity can be directly correlated with the damping properties and, consequently, the quantity of energy dissipated. Because of the activity of seismic dangers, the viscous damper's response is thought to be out of phase with those. This is due to the fact that the damping device's damping forces changes inversely with a tall building's dynamic lateral displacements. For a clearer understanding, picture a building that is trembling laterally during an earthquake. When the building's deflection is at its highest, the stress in lateral load-resisting components like frame columns reach its maximum. When a fluid viscous damper reaches its maximum deflection, its damping force will be zero, which will cause the damper stroking velocity to zero when the building reverses direction. When the building returns to its natural upright position, maximum damper force will be experienced at maximum velocity while moving in the opposite direction. At this stage, the lateral load-resisting elements' stresses are at their lowest. As a result, when the building travels from its resting position to its maximum lateral deflection position, the damping supplied by the device changes from maximum to minimum. Examine a few research studies to learn more about working on FVD. The authors of this paper examine FVD, its use, and its impact in various scenarios.
