It can be found that the closed TLCD is more flexible in practice than the open one; therefore it might have high potential in various applications. The design charts of the open and closed TLCD’s are also presented and can be used as the design guide in practice. A simple pendulum-like model test is carried out to study the dynamic behavior and the effectiveness of the vibration control of a TLCD.application/pdf132919 bytesapplication/pdfzh-TW國立臺灣大學土木工程學系暨研究所reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/2850/1/922211E002074.pdf
