Performance Analysis of RCC Structure Installed with Damping System using Response Spectrum Analysis

There are many such devices developed in Structural Engineering which serves the purpose of Structural Safety such devices are dampers, base isolators, bracings, springs etc. Another such device recently developed is NSD (Negative Stiffness Device). The NSD is a device that produces a force which is in the same direction as the imposed displacement thus the name “negative stiffness.� This new study was done to know the efficiency of using NSD for controlling vibration of RCC structure in comparison with other existing damping systems. Response spectrum analysis and designing is done using Etabs software. Comparison is done for models of fixed base, base isolation, fluid viscous damper and negative stiffness damper. Four models each with different dampers are prepared for analysis and design of G + 14 storey building for that M25 concrete grade and Fe 415 steel grades are taken. Dampers are designed and applied to the structures. The Comparison of storey acceleration, storey forces, storey displacement and time period are done.
