项目摘要

Recently 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, aclear explanation of their behaviours 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 purposes of this study are to clarify the behaviors of structures or equipments, piping systems in a building under severe earthquake ground motions, and to discuss a synthetic evaluation for some vibration controlling techniques and their applications. The contents of this study are divided into following each subjects :1. Studies on the earthquake loading of building to having unbalance for the structural distributions along the heights.2. 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.3. Studies on the vibration control by the HィイD1∞ィエD1 for equipments under severe earthquake ground motions.4. Studies on dynamic experiments and analyses for the vibration behavior and isolation equipment of wooden space structure.

最近，在强烈的地震作用下，建筑物内的结构或设备、管道系统倒塌而造成损坏。因此，特别重要的设备在基础上被隔离，或者控制那些振动。然而，对其在强烈地震下的行为尚未做出明确的解释，隔震或振动控制技术对强烈地震地震动的效果还不能说是足够的。本研究的目的是阐明建筑物中的结构或设备、管道系统在强烈地震地震动下的行为，并讨论一些振动控制技术的综合评价及其应用。本研究的内容分为以下各课题： 1．结构沿高度分布不平衡的建筑物地震荷载研究； 2．建筑物结构或设备、管道系统新型阻尼器的开发研究。这些阻尼器有主动、半主动或被动类型。3．强震地震动条件下HィイD1∞ィエD1设备振动控制研究。 4．木空间结构振动行为及隔震装置动力试验与分析研究
