| 中文摘要: |
| 研究了复杂结构的空间部分相干多点激励平稳随机地震响应。该方法同时计入了振型间和激励间的耦合项，是完全的ＣＱＣ算法，可以方便高效且高精度地算出各种响应量的自谱和互谱。 |
| 英文摘要: |
| The stationary random responses of complex 3D structures subjected to spatially coher-ent excitations are investigated and the pseudo-excitation algorithm is derived.This algo-rithm involves the cross-correlation items both between the participant modes and betweenthe excitations,and so it is a sort of complete CQC method.The auto-or cross-psd of var-ous structures can be computed efficiently and accurately. |
