The purposes of this study are to clarify the behaviors of structures or equipments, piping systems in a building under the earthquakes, and to discuss a synthetic evaluation for some vibration controlling techniques and their applications. Damages due to collapse of structures or equipments, piping systems in a building under severe earthquake ground motions. So for, particularly important equipments are isolated at the foundation, or controlling those vibrations. However, a clear explanation of their behaviors during severe earthquakes has not been made, and the effect of the isolation or the vibration controlling techniques for severe earthquake ground motions can not be said to be sufficient.The contents of this study are divided into following each subjects :1. Studies on the earthquake loading of buildings to having unbalance for the structural distributions along the height. The structural characteristics are distributions on mass, damping, stiffness, and strength along the height.2. Studies on the torsional response characteristics of buildings with the eccentricities of additional mass and shear wall.3. Studies on the development of new type dampers for structures or equipments, piping systems in a building. These dampers are active, semi-active, or passive types.4. Studies on the vibration control by the H ∞ for equipments under earthquake ground motions.5. Studies on dynamic experiments and analyzes for the vibration behaviors and isolation equipments of wooden houses.

本研究的目的是阐明建筑物结构或设备、管道系统在地震作用下的行为，并讨论对一些振动控制技术及其应用的综合评价。建筑物中的结构或设备、管道系统在强烈地震地面运动下倒塌造成的破坏。因此，特别重要的设备是在基础上隔离，或控制那些振动。然而，对于它们在大地震中的行为还没有得到明确的解释，对于大地震地面运动的隔震或减振技术的效果也不能说是足够的。本文的研究内容分为以下几个方面：1.结构沿高度分布不平衡的建筑物地震荷载研究。其结构特点是质量、阻尼、刚度和强度沿高度的分布。研究附加质量和剪力墙偏心结构的扭转反应特性。建筑结构、设备、管道系统用新型阻尼器的开发研究。这些阻尼器分为主动、半主动或被动类型。地震地面运动下设备的H-∞振动控制研究。对木结构房屋的振动特性及隔震装置进行了动力试验与分析研究。
