Abstract
TLCD is a good alternative to TMD for control of structures because of its cost efficiency, ease of installation, little maintenance requirement, potential for multiple usage, and ease of re-tuning. In this study, the control performances of TMD and TLCD are evaluated and compared for seismically excited structures. Results show that TLCD is more effective than TMD for interstory drift control while TLCD is as effective as TMD for acceleration control. In special. it is shown that interstory drifts are maximally controlled in lower floors and accelerations are reduced most in upper floors. This indicates that TLCD is an effective controller for earthquake-induced structures in terms of structural safety as well as serviceability.
