Basic research on connected control for multi high-rise buildings aimed at living comfort-ability and safety against strength earthquakes or strong winds

主动质量阻尼器的使用主要是为了减小中小烈度地震或大风引起的高层建筑的振动，但由于很难获得足够的控制力来控制这些运动，主动质量阻尼器对超高层建筑中发生的大地震或极低频振动运动的减振效果不佳。为了解决这些问题，本课题提出了关联控制方法(CCM)。该方法通过分别安装半主动、主动或混合控制装置的通道将两个或多个建筑连接起来，通过它们之间的相互作用力对建筑进行控制。该方法具有在低频下获得足够的控制力的优点。此外，这种方法还将具有更多的优点，如不需要风激励就可以提供舒适的生活，以及在塔与塔之间连接桥梁的立方人行道上生活方便。在本研究中，磁流变阻尼器被开发为构建CCM系统对多建筑结构地震反应控制的有效半主动控制装置之一。利用修正的神户波和EI Centro波对四个建筑结构的地震反应控制进行了仿真，验证了其有效性。研究结果如下：(1)CCM对多层建筑结构的地震反应控制是有效的。(2)只有一个磁流变阻尼器可以控制四个建筑结构的两种振型。(3)对修正地震波的试验结果表明，研制的磁流变阻尼器适用于半主动控制，对地震反应控制是有效的。

The active mass dampers are used mainly in order to reduce the vibration in high rise buildings caused by small to mid strength earthquakes or strong wind, however this equipment has been rendered ineffective in mitigating the vibration caused by large earthquakes or very low frequency vibratory movements which occur in ultra-tall buildings, because it becomes difficult to obtain enough control force to control these movements. In order to solve these problems, Connected Control Method (CCM) has been proposed in this research project. According to this method, two or more buildings are connected by a passage installed with semi-active, active or hybrid control devices, respectively, and the buildings are controlled through the interactive forces among them. This method has the merit of obtaining sufficient control force under low frequency operations. In addition, it is also expected that this method will have further merits such as a providing comfortable living without the efforts of wind excitation, and convenient living with cubic walkways using connecting bridges between towers.In this research, the MR damper has been developed as one of effective semi-active control devices for constructing the CCM system to seismic response control of multi-building structures. Effectiveness of seismic response control for a four building structures is demonstrated by simulation using the modified Kobe and EI Centro waves. The following research results were obtained(1)The CCM is effective for seismic response control of multi-building structures.(2)It is demonstrated that only one MR damper controls two vibration modes of four building structures.(3)From the experimental results applying the modified earthquake wave, it is found that the developed MR damper is adapted to the semi-active control and is effective for seismic response control.
