基于灰关联的砖混建筑抗震易损性指标重要性研究

Research on the Brick Building Antiseismil Vulnerability Assessment and Index Importance Based on Gray Relational Structure

采用灰关联分析法，通过对大量工程震害数据分析，得出了各砖混结构建筑抗震易损性评价指标与震害的灰关联系数，建立了建筑抗震易损性评价指标重要性模型，并以此依据对结构抗震易损性评价指标的影响程度进一步分析，筛选出影响其灾害损失的主要因素，使得砖混结构建筑抗震易损性预测结果定量化、合理化。

By using the gray relational analysis method and through the analysis of earthquake data of a large number of projects, a seismic vulnerability assessment of building the model is established, the gray relational coefficient of the brick building seismic vulnerability evaluation is drawn and the importance of the seismic behavior indicators is analyzed, the main pointers of the brick building seismic vulnerability evaluation are riddled, and a quantitative and rationalized method to analyze the seismic vulnerability of buildings is provided.
