| 摘 要： | 本文对五种等效线性化方法——割线刚度法、Hwang的经验系数法、平均刚度和能量法、Iwan的经验系数法、平均刚度和阻尼法的计算精度进行了统计分析。以误差的均值和变异系数作为评价标准，研究不同延性、不同结构周期、不同阻尼比对这些简化计算方法计算精度的影响。

| Abstract: | The computation precision of five equivalent linearization methods, i.e. secant stiffness method, the empirical method by Iwan, the empirical method by Hwang, the method based on the average stiffness and energy, and the method based on the average stiffness and damping coefficient are evaluated using the average error and variation coefficient as the evaluation standard. Influences of displacement ductility demand, structual periods and damping ratio on the results of the simplified methods are analyzed. |
