This research consists of mainly following two parts of which results are as follows :In order to use Active Mass Dampers (AMD) for the seismic response control of structures, excessive auxiliary mass displacements must be avoided even under a high level of excitation, which becomes a critical factor in the event of strong earthquakes. The control algorithm for the full-scale multi-story steel frame test structure at DPRI, Kyoto University takes advantage of a nonlinear control scheme based on a variable gain method to overcome this difficulty. The nonlinear control scheme based on a variable gain method to overcome this difficulty. The nonlinear control used in the test achieves effective use of AMD with a limited displacement range of the auxiliary mass for structures under various levels of seismic input. The structural control test is conducted to verify the efficiency of the variable gain control scheme when used with the full-scale test structures. The test result using a seismic record shows the effectiveness of the control method, especially when subjected to a strong earthquake excitation.Control methods for seismic response reduction using an actuator installed between two buildings are investigated. Simultaneous control of two structures is possibly more difficult than controlling a single building. In this research, response of two real buildings consisted of 3-story and 5-story connected by an actuator is studied by numerical simulation and experiments. Two robust control theories are applied to the numerical calculation. The one is the H-infinity norm optimal control theory which is essentially a frequency domain design, and the other is the Sliding mode control theory, which is a design method in the time domain, Application of these theories proves to effectively reduce the seismic response.

这项研究主要包括以下两个部分，结果如下：为了使用主动质量阻尼器（AMD）进行结构的地震反应控制，即使在高度的激发下，也必须避免过多的辅助质量位移，这将变成发生强烈地震的关键因素。 DPRI的全尺度多层钢框架测试结构的控制算法，京都大学利用基于可变增益方法的非线性控制方案来克服这一难度。基于可变增益方法的非线性控制方案来克服这一难度。测试中使用的非线性对照可有效使用AMD，而在各种地震输入水平下，辅助质量的位移范围有限。进行结构控制测试以验证与全尺度测试结构一起使用时可变增益控制方案的效率。使用地震记录的测试结果显示了控制方法的有效性，尤其是在受到强烈地震激发的情况下进行。对控制方法减少地震响应的方法，使用两座建筑物之间安装的执行器进行了降低。同时控制两个结构可能比控制单个建筑物更加困难。在这项研究中，通过数值仿真和实验研究了两座实际建筑物的响应，由执行器连接的三层楼和5层楼层组成。两种健壮的控制理论应用于数值计算。一个是h-侵点规范最佳控制理论，它本质上是频域设计，另一个是滑动模式控制理论，它是时间域中的一种设计方法，这些理论的应用被证明可以有效地减少地震响应。
