本文探討如何應用力耦合分析於大型結構,以確保結構之安全性。考慮當大型結構經模型縮減法並且適當的耦合,進而可得整體分析模型並進行後續響應分析,利用其響應資料可估測出構件間的耦合力與動力反應,以判斷結構是否符合可靠性。本文基於前人所提出的驗證方法,如構件之局部平衡檢驗、介面力之平衡檢驗以及構件上重心加速度與介面力之檢驗,上述方法皆利用動態響應資料來重建各構件上的受力情形以進行驗證;然而經數值模擬得知上述數種驗證法無法有效的彰顯出模型縮減誤差之情況,因此,本文提出全結構之平衡檢驗法,以有效反映模型縮減前後的誤差。經數值模擬結果顯示,本文所提出的全結構之平衡檢驗法能有效的反映出模型縮減所產生之誤差,進而可對力耦合分析進行有效性的判斷。
This thesis discusses the application of coupled loads analysis for large structure safety evaluation. Consider a structure with model reduction method and proper coupling, the entire analytic model of a structure could then be obtained for further response analysis. The corresponding response may be employed to estimate the couple load and the dynamical behavior between the structure parts, so as to confirm the structure reliability. The traditional verification methods can be used to reconstruct the load distribution of every component from dynamic response data. The error due to the model reduction, however, could not be manifest. To improve of effectiveness of the error due to before and after the model reduction, the entire structure equilibrium method is proposed in this thesis. Numerical simulations confirm the validity of the proposed entire structure equilibrium method for improvement of the reliability of couple loads analysis.
