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

主动质量阻尼器主要用于减少由小到中等强度的地震或强风引起的高层建筑物中的振动，然而，这种设备在减轻由大地震或发生在超高建筑物中的非常低频率的振动运动引起的振动方面已经变得无效，因为难以获得足够的控制力来控制这些运动。为了解决这些问题，本课题提出了关联控制方法（CCM）。根据该方法，两个或多个建筑物通过分别安装有半主动、主动或混合控制装置的通道连接，并且通过它们之间的相互作用力来控制建筑物。该方法具有在低频操作下获得足够的控制力的优点。此外，还期望这种方法将有进一步的优点，如提供舒适的生活没有风激励的努力，和方便的生活与立方走道使用连接桥梁之间的塔。在本研究中，MR阻尼器已被开发为一个有效的半主动控制装置，用于构建CCM系统的多建筑结构的地震反应控制。采用修正后的科比波和EI Centro波对一个四层建筑结构进行了地震反应控制的仿真研究，验证了该方法的有效性。研究结果表明：（1）CCM对多层建筑结构的地震反应控制是有效的。(2)It结果表明，仅用一个磁流变阻尼器就能控制四个建筑结构的两个振动模态。（3）在修正地震波作用下的试验结果表明，所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.
