摘要
运用响应谱分析方法对管道地震的分析提供了一个新的途径。针对管道地震分析中地震谱的定义、工况的设置以及应力合成方法等参数的设定,利用响应谱法及等效静力法分别计算了地震对管系的作用方式及作用结果。计算结果表明:响应谱法由于考虑了动态效应,因此结果要比等效静力法更为全面和准确。响应谱可以作为一种更先进的管道抗震评定方法来取代等效静力法。
Response spectrum method was supplied for seismic analysis of piping. With respect to the definition of earth quake spectrum, selection of working condition and composition of stresses, by using response spectrum method and equivalent static force method individually, calculation of the action of earthquake to piping and the results were demonstrated. It as shown that in view of account of dynamic effect, the result from response spectrum method is more accurate than that from equivalent force method, thus, as a more advantageous method, response spectrum method can substitute for equivalent force method in seismic assessment of piping.
