Abstract

As an important part of nonstructural components, the seismic response of indoor water supply pipes deserves much attention. This paper presents shaking table test research on water supply pipes installed in a full-scale reinforced concrete (RC) frame structure. Different material pipes and different methods for penetrating the reinforced concrete floors are combined to evaluate the difference in seismic performance. Floor response spectra and pipe acceleration amplification factors based on test data are discussed and compared with code provisions. A seismic fragility study of displacement demand is conducted based on numerical simulation. The acceleration response and displacement response of different combinations are compared. The results show that the combination of different pipe materials and different passing-through methods can cause obvious differences in the seismic response of indoor riser pipes.

基于振动台试验的全尺寸RC框架结构供水管道抗震性能评价

摘要

室内给水管道作为非结构构件的重要组成部分，其地震响应值得关注。本文介绍了安装在全尺寸钢筋混凝土（RC）框架结构中的供水管道的振动台试验研究。结合不同材质的管道和不同穿透钢筋混凝土楼板的方法来评估抗震性能的差异。讨论了基于测试数据的地板响应谱和管道加速度放大系数，并与规范规定进行了比较。基于数值模拟对位移需求进行地震易损性研究。比较不同组合的加速度响应和位移响应。结果表明，不同管道材料和不同穿通方式的组合会导致室内立管的地震响应存在明显差异。
