| 摘 要： | 采用质点系模型,利用时程分析法,分别使用以加速度和速度峰值为标准化的地震波,对两种层间侧移刚度分布不同的钢框架模型做了详细深入的分析和对比。结果表明,以地震波速度峰值作为度量评价地震波强度的方法,比以地震波加速度峰值作为度量评价地震波强度的方法更具有说服力;各层损伤情况与层间刚度相对值有很大关系,即刚度均匀的结构损伤主要集中在下部,而刚度相对不均匀的结构损伤与此不同。通过分析验证了"输入能量只与结构总质量和第一周期有关"的秋山宏见解。

| Abstract: | Two steel frames with different interlaminar stiffness are considered as the mass-system model.The peak value of the velocity and acceleration of the seismic wave are investigated separately.The time-history analysis is employed to calculate the seismic response of two models.Particular analysis are carried out by comparison.Results indicate that the evaluation method for the intensity of seismic waves by using the velocity peak value is more convincing than the acceleration peak value.And the damage extent... |
