| 摘 要： | 研究了应用主动锚索控制装置控制相邻建筑地震响应的有效性。首先，建立了主动锚索－相邻建筑系统的运动方程；然后应用广义振型分析方法，寻求了主动锚索联结的相邻建筑的力学特性，特别是振型阻尼比；最后，在频率域内应用广义振型分析与虚拟激励相结合的方法，建立了主动锚索控制装置联结相邻建筑的随机地震响应的分析方法。应用本文建立的公式，我们编制了计算机程序，进行了广泛的参数研究，以评价控制装置的有效性，并确定最优传感器类型及控制装置参数。研究表明，如果应用速度传感器，并能适当地选择主动锚索控制器的参数，则可以显著地提高系统的振型阻尼比，减小两个结构的地震响应。

| Abstract: | An investigation is carried out on the effectiveness of using active tendon devices to link adjacent buildings for seismic response control. The equations of motion of active tendon-adjacent building systems are established first. Dynamic characteristics, in particular the modal damping ratios, of active tendon-linked adjacent buildings are then sought using a generalized modal analysis method. Random seismic response of adjacent buildings linked by active tendon devices is finally determined by a combination of the generalized modal analysis method and a pseudo-excitation method in the frequency domain. Based on the derived formula, a computer program is written and extensive parametric studies are performed to assess the effectiveness of active tendon devices and to identify the optimal type of sensors and the beneficial parameters of devices. It is showed that the modal damping ratios of the system can be significantly increased and the seismic responses of both buildings can be substantially reduced if velocity sensors are used and the parameters of active tendon devices are selected appropriately. |
