五十子幸树（Kohju Ikago）

    日本建筑学会结构振动控制委员会主席

    日本东北大学灾害科学国际研究所教授

五十子幸树(Prof. Ikago Koju)博士为日本东北大学灾害科学国际研究所教授，是日本建筑学会里从事结构振动控制研究的关键人物之一，也是灾害科学国际研究所在结构抗震领域的学科带头人，其研究团队开辟了土木工程领域的惯容减震研究，研发了世界上第一款产品级的惯容减震器，设计了位于日本仙台的世界上第一栋使用惯容系统的土木工程结构。  

2018年五十子幸树教授入选国家外国专家局高端外国专家项目，每年访问同济大学的时间超过30天，合作双方在惯容减震设备的开发和设计方面开展了合作研究。
