A Study on the Vibration Control of Earthquake Responses for Structures and Equipments, Piping Systems in a Building

本文的研究目的是阐明建筑物结构或设备、管道系统在地震作用下的性能，并对一些振动控制技术及其应用进行综合评价。在强烈地震动下建筑物的结构或设备、管道系统倒塌造成的损害。所以，特别重要的设备在基础上被隔离，或者控制这些振动。然而，对于它们在强震中的行为还没有一个明确的解释，隔震或振动控制技术对强震地面运动的影响还不能说是充分的。本研究的内容分为以下几个主题：1。沿高度分布的建筑物地震荷载对不平衡的影响研究。结构特性是质量、阻尼、刚度和强度沿高度的分布。考虑附加质量和剪力墙偏心的建筑物扭转响应特性研究。建筑物结构或设备、管道系统用新型阻尼器的开发研究。这些阻尼器有主动、半主动和被动三种类型。地震地震动作用下设备的H∞振动控制研究。对木质房屋的振动特性和隔震装置进行了动力试验和分析。

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.
