由于互联设备在最近的地震中发生故障，人们怀疑在强地面运动期间柔性导体与设备的地震相互作用可能会导致额外的不可预知的力，导致它们互联的设备损坏或倒塌。本文介绍了通过对加拿大不列颠哥伦比亚省变电站中使用的一类柔性导体和相关的500千伏互联设备进行几次振动台试验来研究柔性导体的动态行为的结果。试件由设备的大型模型和实际尺寸的柔性导线组成。振动台输入记录是为符合IEEE规定的反应谱而产生的合成地震。研究表明，在评估互联设备的抗震能力时，必须考虑柔性导体的动力效应。
Due to failures of interconnected equipment in recent earthquakes, it is suspected that the seismic interaction of the flexible conductors with the equipment during a strong ground motion could cause additional unpredicted forces, resulting in damage or collapse of the equipment they interconnect. This paper presents the results of an investigation into the dynamic behavior of flexible conductors by performing several shake table tests on a class of flexible conductors and the relevant 500-kV interconnected equipment used in substations throughout the province of British Columbia in Canada. The test specimen consisted of large scale models of the equipment items and the actual size flexible conductors. The shake table input records were synthetic earthquakes generated to fit an IEEE prescribed response spectrum. This investigation showed that the dynamic effect of flexible conductors must be considered when evaluating the seismic capacity of interconnected equipment.
