不同恢复力模型对能量反应谱特征的影响
|
摘要
采用4种不同形式的恢复力模型,分别选择不同的模型特征参数,计算具有不同强震持时和频谱特性的地震动记录的能量反应谱,分析了不同的恢复力模型及其特征参数对能量反应谱的影响。结果表明,不同恢复力模型结构计算得到的输入能量谱和滞回能量谱形状相近,当周期小于谱峰值对应的周期时理想弹塑性模型和双线性模型相对其它模型属于非保守模型。研究结果对基于能量的弹塑性地震反应分析方法的深入研究具有一定的意义。
With 4 different forms of restoring force model,dif fe rent model parameters were chosen to calculate different types of earthquake dur ation and spectrum features,the different characteristics of the restoring forc e model and its parameters on the energy response spectrum were analyzed.The re sults show that the shape of the input energy spectrum and hysteretic energy spe ctrum calculated by different models are similarly,and when the period is less than the corresponding period of spectral peak value,bilinear model and elastic-perfectly plastic model are not conservative relative to other models.The res ults are meaningful for the energy-based analysis of seismic response of the in-depth study.
