室内管道系统抗震研究综述

根据最新震害统计资料发现，非结构构件在地震中造成的经济损失远大于结构构件。非结构构件按照地震反应特征可分为位移敏感型构件和加速度敏感型构件。其中，位移敏感型构件的破坏多受层间位移角控制，主要采用拟静力试验进行研究；加速度敏感型构件的破坏多受楼面加速度的控制，主要采用振动台试验进行研究。室内管道系统是非结构构件的重要组成部分，室内管道系统中的立管和水平管分别属于位移敏感型和加速度敏感型构件。本文系统地论述了近年来国内外学者开展的关于室内管道系统的抗震研究工作，并对室内管道系统下一步的研究工作提出了建议。

A Review of Study on Seismic Performance of Indoor Piping System

According to the latest seismic damage statistics,the economic loss caused by nonstructural components in the earthquake is much greater than that caused by structural components. The indoor pipeline system is an important part of nonstructural components. In recent years,the seismic problem of non-structural members has attracted extensive attention from scholars at home and abroad. Indoor pipelines can be divided into displacement sensitive members and acceleration sensitive members according to the seismic response characteristics. The damage of displacement sensitive members is mainly controlled by the story drift angle whereas the damage of acceleration-sensitive component is controlled by the floor acceleration. Quasi——static test is used to study seismic performance of displacement sensitive members and shaking table test for acceleration sensitive members. The vertical pipe and horizontal pipe belong to displacement sensitive and acceleration sensitive components respectively. In this paper we review the past research work on indoor piping system carried out by domestic and foreign scholars in recent years,and put forward some suggestions on the further research work of indoor piping system.
