Overview

Numerical investigation reveals that fluid viscous dampers enhance seismic response in high-rise structures, indicating better safety measures.

Key Points

  • This research aims to assess how different placement strategies of fluid viscous dampers impact the seismic performance of an irregular high-rise composite building.
  • Developed a high-fidelity three-dimensional finite element model of a 20-story structure.
  • Conducted a comparative analysis between conventional and enhanced structural systems utilizing FVDs.
  • Performed nonlinear time-history analysis using ground motion records from the 2023 Kahramanmaraş earthquake.
  • All FVD configurations showed significant performance gains in seismic response.
  • Peak story displacements and interstory drifts were reduced by up to 55%.
  • Base shear was lowered by nearly 50% with comprehensive damper installations.
  • Targeted placement in critical stiffness zones yielded substantial benefits with fewer devices.
