| 摘 要： | 地震易损性分析是评估结构地震灾害损失的关键。应用PKPM软件设计了不同设防烈度的6个16层剪力墙结构。应用增量动力法求得各结构在不同罕遇烈度地震作用下的最大层间位移角,回归分析给出了最大层间位移角与地震作用加速度峰值的关系式。以最大层间位移角为整体性能指标,进行结构地震易损性分析,给出了结构地震失效概率关于地震作用加速度峰值的计算公式。计算得到了不同设防烈度剪力墙结构在罕遇地震作用下的震害矩阵,为评估框架-剪力墙结构的地震灾害损失,提供了基础数据。

| Abstract: | Seismic fragility analysis is the key to estimate earthquake loss of structure.Six 16-story typical shear wall structures whose seisimc forliliation intensities are different were designed by use of the structure-designing software PKPM.Based on incremental dynamic analysis,the maximum interstory drife ratios were calculated if shear wall structures would suffer different degrees of seldom occurred earthquake.Relation formulas of maximum interstory drife ratios and earthquake acceleration amplitude were obt... |
