반복적인 동적 축소법과 대형 구조물 해석을 위한 부구조화 기법의 적용

다국어 초록 (Multilingual Abstract)

This work presents an iterative dynamic condensation procedure combined with sub-structuring scheme for large structures. Iterative dynamic condensation techniques are usually more efficient than others because the dynamic condensation matrix is updated repeatedly until the desired convergent values are obtained. However, using these methods simply for large structures causes very expensive computational cost and even makes analyses impossible because of the limited computer storage. Therefore, the application of subtructuring scheme is necessary to calculate eigenproperties for large structures. Because the large structures are subdivided into several (or more) sub-domains, the construction of dynamic condensation matrix does not need much computation cost in every iteration. This makes the present method much more efficient to compute the eigenpairs both in lower and higher modes. Numerical examples are applied to demonstrate the features of this method.
