| 摘 要： | 振型和频率仅与质量和刚度有关,由结构外形唯一确定,故称之为特征参量。振型为结构位移的完备正交基,基于振型加载模式的Pushover方法较其他方法更加合理。采用结构质量参与系数控制振型参与计算数量,振型数有了量化标准,使精度满足安全需要。最后通过实例阐述多模态自适应Pushover方法的实施过程。

| Abstract: | Mode and frequency are only related with mass and stiffness,which are decided by structure shape.So the mode and frequency are also called character parameters.Because mode is self-contained orthotropic matrix,loading based on it is more rational than other loading method.Mass participating ratio is utilized to control the quantization mode number.As a result,calculating mode has measurement criteria,and the precision meets the safety demand.At last,an engineering example is employed to illustrate the multiple mode adaptive pushover method. |
