Numerical Analysis Of Viscous Wall Dampers On Steel Frame

The structure is designed to minimize component damaged, one of them is using a damping system. Viscous Wall Damper is one of the damping systems, using high viscosity liquids as dampers. The viscous wall damper is represented by an Exponential Maxwell Damper model. Much of the literature shows the ability of viscous wall damper by experimental studies, but few of them had discussed numerically. This article will present an analytical model of the viscous wall damper, add viscous wall damper element to an existing frame and numerical analysis. The analysis was performed by a computer application on a steel space frame that excited a combination of three earthquake types. The influence of Viscous Wall Damper showed that a significant decrement of displacement u1 at the structure with Viscous Wall Damper in X & Y direction (50,78%) and with Viscous Wall Damper in Y direction (23,96%). The decrement displacement happened in all structure. At the end of the analysis shows the reduced of the structure periods, the structure response (displacement, velocity, and acceleration). All these results conclude that the structural components damaged due to loads can be greatly reduced.
