  • Abstract:
  • It is well understood fact that all structures inherently dissipate and absorbs energy induced due to external loading such as earthquake shaking by its ability to deform, flexibility and strength. The performance of the buildings can further be improved by controlling seismic response using viscous fluid dampers. Focused mainly on their nonlinear behavior; this study will demonstrate the advantages of viscous dampers on steel composite buildings subjected to few sets of ground motions. The analysis was carried out using ETABS software, using the nonlinear dynamic analysis (modal time-history) method for few sets of ground motions download from PEER database. Earthquakes have devastating impact on the dynamic response of buildings due to its unpredictability and random nature. In this study, two cases have been studied in order to make a significant comparison: the actual building without viscous dampers, and the building with dampers installed. Results were exported for both cases and shown in terms of story displacements, story accelerations and inter story drifts, and the plot of the cumulative energy of the system. The results show a significant reduction in ductility demand, as well as their response such as accelerations, displacements and drifts.
