摘要

A large number of ancient five-storied pagoda in Japan has survived strong earthquakes over centuries, proving its structural advantage. Typical structure of pagoda, consisted of self--supporting outer tower and inner core post, yields friction and collision between outer and inner structures. Similar mechanism can be applied to modern buildings exited by earthquakes or strong wind to absorb response energy efficiently. This paper presents a passive vibration control system which utilize the above-mentioned mechanism. The system consists of joint dampers which connected two high rise towers of the same height. The dampers locate every three to four stories between two towers. The method to obtain the optimum distribution of joint dampers is described. An example is presented through a numerical simulation showing the effectiveness of the presented scheme.
