partiality symmetrical degree偏心对称度
3)centrali ty碰撞对心度
4)degree of rupture center symmetry断裂中心对称度
5)normalized stiffness eccentricity相对刚度偏心距
1.The ratio spectrum distribution pattern and the effects of normalized stiffness eccentricity and rotation frequency ratio on spectrum amplitude are discussed by use of statistic analysis of 30 recordings under bidirectional earthquake excitation in the cases of hard sit.通过对硬土、中硬(软)土、软土3类场地60条双向地震动的弹性比值谱统计平均结果,分析3类场地比值谱的谱值分布特征及相对刚度偏心距、扭转频率比对谱值及谱值分布的影响。
6)relative velocity/instantaneous center相对速度/瞬心
