Abstract

This study investigates the performance of annular cylindrical liquid column dampers (ACTLDs) for vibration suppression of structures with experimental tests. To this aim, a shear-type frame consisting of a top and bottom plate with four columns is constructed in laboratory and is exposed to ground motion with different directions. Dynamic characteristics of the shear frame are first extracted by the finite element analyses, ambient vibration tests and shaking table tests. Then, with employing the resonant frequency of the shear frame, resonant frequency, head-loss coefficient, damping ratio and water height–frequency diagram of the designed ACTLD are determined experimentally by the shaking table tests. Finally, ACTLD-shear frame coupled system is considered to extract the first natural frequencies and related mode shapes to evaluate the performance of ACTLD in suppressing vibrations of the model structure under different excitation angles of motion between 0° and 90° with increment of 15°. The acceleration and displacement time histories are examined to obtain damping of the structure. Results show that proposed ACTLD is good enough to suppress vibrations due to the ground motion with inclined exposing direction to the structure.
