一、前言拉索系统用于主动结构控制的可行性,已为过去几年中一系列的模型试验所证实。近来,在一个专用的六层建筑物上进行了主动拉索系统的原型试验。主动拉索系统由在闭环中与数字计算机和速度或加速度传感器联接的伺服控制的液体作动器驱动。原型结构主动拉索系统的初步设计,是通过利用原型结构与试验室中模型试验结构之间的相似性而建立在先前试验结果的外推数据基础上的。事实上,这种做法只适用于有限的情形。为了实用的目的,需要 I. INTRODUCTION The feasibility of the cable system for active structural control has been confirmed by a series of model tests in the past few years. Recently, prototype tests of active cable systems were conducted on a dedicated six-story building. The active cable system is driven by a servo-controlled liquid actuator that is coupled in a closed loop with a digital computer and a speed or acceleration sensor. The preliminary design of the prototyping active cable system is based on the extrapolation of the previous test results by using the similarity between the prototype structure and the experimental structure in the laboratory. In fact, this approach only applies to limited situations. For practical purposes, need
