摘要
假定双向地震动模型为平稳白噪声模型 ,考虑地震动的空间相关性 ,用随机过程理论建立了双向地震动作用下结构反应的组合方法 ,给出了双向地震动输入下振型相关系数公式 .并选一 1 2层偏心结构进行计算 ,与振型位移法结果比较 。
It is assumed that the double translational components of seismic are stational white noise and the correlation between the input components is considered. The combination method for structural response excited by double earthquakes is proposed based on random vibration theory and the mode correlation coefficient is derived. The response of a 12 story eccentrical structure is calculated and the result is compared with result of random mode displacement method.The results of two methods are very closed.
