【摘要】：HAZUS作为一款多灾害损失评估软件,在世界范围内得到了广泛应用。确定结构的地震易损性函数是HAZUS软件进行地震损失评估的关键。然而,现有的传统地震易损性分析结果无法满足HAZUS的格式要求。为此,该文提出一种与HAZUS相容的地震易损性分析的简化方法,该方法直接利用传统的地震易损性分析结果,通过能力谱方法确定地震动记录的谱位移作为其参数,转化得到满足HAZUS格式要求的地震易损性结果。为说明该文提出的方法,选择4个不同高度的钢筋混凝土框架结构作为算例,并将该文方法的分析结果与HAZUS软件提供的地震易损性曲线进行对比。结果表明:由于分析方法和分析对象的不同,HAZUS相容的地震易损性结果与HAZUS软件所提供的地震易损性结果之间存在较为明显的差异。
[Abstract]:As a multi-disaster loss assessment software, HAZUS has been widely used in the world. Determining the seismic vulnerability function of the structure is the key to the seismic loss assessment by HAZUS software. However, the traditional seismic vulnerability analysis results can not meet the requirements of HAZUS format. In this paper, a simplified method of seismic vulnerability analysis compatible with HAZUS is proposed in this paper. The method directly uses the traditional seismic vulnerability analysis results and determines the spectral displacement of seismic motion records as its parameters by means of the capability spectrum method. The seismic vulnerability results satisfying the requirements of HAZUS format are obtained. In order to illustrate the method proposed in this paper, four reinforced concrete frame structures with different heights are selected as examples, and the analysis results of this method are compared with the seismic vulnerability curves provided by HAZUS software. The results show that there are obvious differences between the seismic vulnerability results of the different methods and objects of analysis and the seismic vulnerability results provided by HAZUS software.
