Fundamental Research on Seismic Response Control of Multiple Highrise Buildings Connected with Active Controlled Devices

为了控制多层平行布置结构在地震激励下的振动，本文提出了两种振动主动控制和被动振动控制的优化设计方法。在无源控制的情况下，用传统的定点法设计无源器件是非常困难的。本文将遗传算法应用于无源器件的设计。通过仿真和实验(4)、(7)、(11)，验证了遗传算法设计被动控制装置的有效性。在主动控制的情况下，按照作者提出的方法，可以同时控制四个模型建筑的第一阶弯曲和第一阶扭转振型。此外，根据所提出的建模方法，建立了考虑结构一阶弯曲振动和一阶扭转振动的两自由度集中模型。此外，通过使用滤波LQ控制，可以在防止溢出的同时控制结构的振动。该振动控制方法同样适用于不同动力条件下结构平行布置的情况，对保证结构可靠度(1)~(3)、(5)、(6)、(9)、(10)是有效的。研究成果被应用于位于东京市中心的实际三层高层建筑的风振控制(8)。

In order to control the vibration of multi-building structures arranged in parallel under the seismic excitation, this study proposes two methods using active and passive vibration controls for optimal designing control devises. In the case of passive control, it is very difficult to design passive devices by conventional theory using fixed point. In this paper, Genetic Algorithm is used to design passive devices. The effectiveness of GA approach to design the passive control devices is demonstrated through simulation and experiment (4), (7), (11).In the case of active control, according to the authors' proposed method, the lst bending and the lst torsional modes of four model buildings can be controlled at the same time. Besides according to the proposed modeling method, the two-degree-of-freedom lumped model which takes one bending vibration mode and one torsional vibration mode of structures into consideration has been created. In addition by using the filtered LQ control, it is possible to control the vibration of the structures while the spillover is prevented. This vibration control method is applied similarly to any case that the structures with different dynamics are arranged in parallel, and is effective to ensure structural reliability (1)〜(3), (5), (6), (9), (10). The research results were applied for controlling the wind excitation vibration in real triple highrise buildings located in downtown Tokyo (8).
