Research is made on the optimum design method for TLD suppressing vibration of highrise buildings subjected  to seisnuc excitation. The machanism of  TLD system of highrise building vibration mode control is analysed. The design tables about TLD optimum parameters are given by using iteration.  Effect of mode factors is considered on TLD optimum parameters. The design steps of TLD -Highrise buildings system subjected to seismic excitation are given. Eventually, a numerical example of TLD system is used in illustration of their application.
