IMPROVED SUBSTRUCTURING METHOD FOR CALCULATION OF EIGENSENSITIVITY

摘要：

　　Calculation of eigensensitivity is usually time-consuming for a large-scale structure.This paper develops a substructuring method for computing the first-,second-and high-order eigensensitivity.The local area of a structure is treated as an independent substructure to be analyzed.The eigensensitivity of global structure with respect to a design parameter are calculated from the eigensensitivity of a particular substructure that contains the design parameter,thus allowing a significant reduction in computational cost.The accuracy and efficiency of the substructuring method is proved by a frame structure and a highway bridge.
