Abstract

Seismic control of the horizontal and torsional response by cylindrical tuned liquid dampers is studied. The hydraulic pressure model of the cylindrical TLD including pulse pressure and convection pressure is established by membrane analogy method. The torsional model of the cylindrical TLD is obtained based on the quasi-uniform vortex theorem. The equation of motion for the control system considering eccentric torsion effect is derived and the solving method is presented. A 10-story eccentric structure with TLD is analyzed to verify the control performance for the horizontal and torsional coupled system under earthquake. The results show that the coupled response can be reduced effectively and the vortex torsional force by TLD cannot be ignored.
