数値ラプラス変換を利用したマトリックス法による骨組構造の衝撃応答解析 : 第2報,部分構造合成法による解析の効率化

A universal program of this matrix method with numerical Laplace transform was developed in the 1st report. Impulsive responses of simple framed structures can be analyzed with its use. For complex structures or those with a large number of elements, the program takes much cpu-time and extensive memory area. Thus the substructure synthesis method is applied to the matrix method in this paper. A comparison of analytical results obtained from the two programs shows that the new program takes less cpu-time and memory area without sacrificing accuracy. Then this method is applied to recalculation after rearrangement of structures and analysis of structures having the same substructures.
