| 摘 要： | 在地震作用下，抗震支吊架理应保障建筑机电工程设施和管道系统均具备良好的服役性能。因此，对抗震支吊架的抗震性能进行检测至关重要。本文以某典型地下室抗震支吊架为对象开展了顺管向地震模拟振动台试验，通过多工况试验对比分析了不同支吊架的位移和加速度的地震响应。试验结果表明:抗震支吊架显著降低了管道位移，减振率最高可达到96%，但对于加速度响应的抑制作用较小。易损性分析表明:采用成品支吊架时，管道系统在遭受相当于设防烈度的地震作用时会发生严重损伤，而采用抗震支吊架的管道系统能够保全其功能。

| Abstract: | Under earthquake excitations，anti-seismic hanger should be able to ensure that the mechanical and electrical equipment of architecture and piping system can maintain good service performance. Therefore，experimental investigation on the performance of anti-seismic hanger is important for the seismic analysis of piping system. In this paper，shaking table tests of one-way seismic simulation along the pipe direction were carried out to comparatively analyze the displacement and acceleration response of different types of hangers under multi-conditions. Experimental results show that the anti-seismic hanger can significantly reduce the displacement of piping system and the vibration reduction ratio can reach up to 96%，but the reduction effect corresponding acceleration is very small. Fragility analysis shows that the piping system with the finished hanger will be severely damaged when subjected to an earthquake equivalent to the fortified earthquake intensity；however the piping system with the proposed anti-seismic hanger works well. |
