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

博士论文按时完成，并在两种期刊上发表。发表在《工程结构杂志》上的一篇文章展示了高层建筑在采用一层或两层阻尼伸出臂时的地震反应。结果表明，如果在结构中增加一个阻尼支腿，结构的地震反应可以得到一定程度的改善。然而，附加阻尼支腿可以有效地降低最大层间漂移响应。阻尼支腿设计的细节发表在《日本建筑评论》杂志上。提出了几种含屈曲约束支撑的阻尼支腿系统的结构形式。本文以实例为实践工程师提供了较为清晰的设计方法。希望阻尼支腿体系的概念能被更多的日本执业结构工程师学习。这项研究在过去一年的三次会议上提出。在台北和东京举行了两次国际会议，许多外国研究人员和学者参加了会议。在金泽举行的日本建筑学会年会也有很多日本教授和学生参加。观众的反应是积极的，并提出了很多建议。

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.
