This thesis presents the effectiveness of tuned liquid dampers (TLDs) for seismic response mitigation of a reinforced concrete (RC) base-isolated (BI) building. Five and ten stories buildings with base isolation (BI) systems are equipped with TLD having mass ratios of 2, 5, and 10 %. The finite element model of the building, the base isolation system, and the TLD are created and used for nonlinear time history analysis to compute seismic response. Ground motions with different peak ground accelerations (PGA) are used in time history analysis. The parameters of the TLD are varied to find an optimal solution which is the most effective in reducing response parameters such as structural displacement and inter-story drift. The results show that TLDs are effective in reducing the structural displacement of the buildings. The control schemes are, however, not effective in controlling floor accelerations and base shear demand.
