摘要
为比较钢框架结构在近场和远场地震作用下的响应规律,建立了6层钢框架结构,对模型在选取的近场和一般场地震动下采用IDA方法进行地震易损性分析,研究表明,近场地震动下钢框架结构更具易损性;地震易损性函数的离散性参数建议采用分析结果统计值。
In order to compare the response laws of the steel framework under the near-field and far-field earthquakes, 6 layer of steel frame structure is established, the paper adopts IDA method to undertake the seismic vulnerability analysis of the model under the selected near-field and normal field, proves by the research that the steel framework can be easily vulnerable under the near-field earthquakes; the statistic values of the analysis results can be adopted for the dispersive parameter of the seismic vulnerability function.
