Description
Mohamed M Shabib and colleagues present a 2026 numerical study of tuned mass dampers for earthquake protection in twelve-story steel buildings. A tuned mass damper is a heavy mass that sways against a building's motion to cut shaking, without external power. Using nonlinear time-history simulations under scaled earthquake records, the team compared a single damper with multi-damper layouts spread vertically, horizontally, and around the perimeter, in regular and irregular building plans.
For the regular building, a four-corner horizontal layout was tested for mistuning, and a frequency deviation of plus or minus four percent gave the lowest top displacement. For irregular plans shaped like T, C, L, and a stadium, a perimeter multi-damper layout cut maximum top displacement by between 18.3 percent and 52.3 percent, depending on the plan. Torsional rotation fell by between 25.4 percent and 68.0 percent, a large drop in twist, with base shear and acceleration also reduced.
