    Abstract: 針對含多重構造結構系統分析值與測試值之比對識別問題,本研究利用最佳化設計的概念建立適當的目標函數與限制條件將其轉換成數學模式。系統程式中將採用逐次二次規劃法為最佳化演算法並利用MSC/NASTRAN有限元素分析軟體為結構分析工具。為了改善計算效率,結構再分析與靈敏度計算乃採用縮減模態空間的方法。 The Sequential Quadratic Programming is applied to solve the problem of Analysis/Test correlation of structures with multiple configurations in this study. The proposed approaches are the extension of the conventional optimum design methods by considering the objective function and constraints from several configurations simultaneously. A general purpose program utilizing MSC/NASTRAN finite element analysis software for structural analysis was developed to implement the optimum design procedures. In order to improve the computational efficiency, the reduced order modal space method is applied for structural reanalysis and sensitivity calculation.
