Application of damped-outrigger system incorporating buckling-restrained brace in tall buildings

博士论文及时完成，并出版了两份期刊。发表在《工程结构》杂志上的一篇文章介绍了高层建筑在采用一层或两层阻尼支腿时的地震反应。结果表明，如果增加一个减震支腿，可以略微改善建筑物的地震反应。然而，附加的减震支腿可以有效地降低最大层间位移反应。减震支腿设计的细节发表在《日本建筑评论》杂志上。提出了几种设置屈曲约束支撑(BRB)的阻尼式支腿体系结构形式。本文通过几个实例为实际工程人员提供了一种较为清晰的设计方法。在过去的一年里，这项研究在三次会议上进行了介绍，希望能让更多的日本实践结构工程师学习到阻尼式支腿体系的概念。在台北和东京举行的两次国际会议，有许多外国研究人员和学者参加。在金泽举行的日本建筑学会年会也有许多日本教授和学生参加。观众的反应是积极的，并提出了许多建议。

The doctoral thesis was finished in time and two journals were published. The one published in the Journal of Engineering Structures presented the tall building’s seismic response when one or two layers of damped-outriggers are adopted. It has indicated that the seismic response of the building can be slightly improved if additional one damped-outrigger is adopted. However, the additional damped-outrigger can help in reducing the maximum inter-story drift response efficiently. The detail of the damped-outrigger design was published in the journal of Japan Architectural Review. Several configurations of damped-outrigger system incorporating buckling-restrained brace (BRB) were presented. This paper provided a more clear design method with several examples for the practicing engineers. It is hoped that the concept of damped-outrigger system can be learned by more Japanese practicing structural engineers.This research was presented in three conferences during the past one year. Two international conferences hold in Taipei and Tokyo were participated by many foreign researchers and scholars. The Architecture Institute of Japan annual conference hold in Kanazawa was also participated by many Japanese professors and students. The responses from the audiences were positive, and a lot of suggestions were given.
