Abstract: This paper examines the effectiveness of using the TLCD for vibration control of various structural systems under random wind loadings. The effectiveness is indicated by the percentage reduction in acceleration and displacement of the building. The structural systems include frame, shear wall and frame-shear wall systems. A wide range of building heights are considered. These buildings are modeled as shear-flexure cantilever beams, taking into account the effects of the higher modes. The sensitivity of the TLCD to changes in structural periods (which are assumed to be proportional to the structural heights) and damping ratios is also examined. Unlike commonly used lumped-mass studies, a continuous formulation is adopted here which allows for response quantities to be determined along the entire length of the structure. Also the effect of varying the damper position on the damper performance can be examined more readily.
