Predictive Control for Earthquake Response Mitigation of Buildings Using Semiactive Fluid Dampers

Table 1

10-storey base isolated building results. Comparison in terms of mean response peak values ratios: relative displacements, accelerations (at base and top) and base shear force V, in relation to the original structure; and peak device’s force ratio f/W in relation to the structure’s weight W.
