초록
본 연구에서는 개인 컴퓨터의 플래시 메모리가 충분하지 않을 경우 대용량의 플래시 메모리를 필요로 하는 구조해석을 컴퓨터 프로그램으로 수행하는 방법론을 연구하였다. 이러한 문제점의 해결방안으로 강성행렬의 블록화기법 -강성행렬이 몇 개의 블록으로 나뉘고 각각의블록에 대하여 행렬분해가 수행되는 방법- 을 제안하였으며 제안된 방법론을 바탕으로 컴퓨터 프로그래밍이 가능한 알고리즘을 제시하였다. 끝으로, 본 연구를 바탕으로 구조해석 프로그램을 개발하였으며 몇 가지 기초적인 구조해석 예제를 통하여 개발 알고리즘의 정합성 및효율성을 확인할 수 있었다.
Abstract
In this study, we studied how to perform the structural analysis which need a large-capacity flash memory with the computerprogram when the flash memory storage of a personal computer has no enough room for the analysis of structure. As one of thesolutions of this problem, the blocking method of stiffness matrix, which is a method that stiffness matrix is divided by a fewblocks and each block is sequentially used for the calculation of matrix decomposition, is proposed and an algorithm available incomputer program is derived on the method. Finally, A structural analysis program (sNs) based on this study is developed and thecorrectness and efficiency of the algorithm is founded through some examples which are fundamental in structural analysis.
