I have a lot of free time on my hands, so I've been playing with OpenFOAM and Blender and etc.
This is the building strength analysis Vol01 simulation.
I confirmed the difference in strength depending on the method of connecting columns and beams using PrePoMax.
There are several types of column and beam connections.
This time I will use the ancient Japanese method of mortise and tenon connection, and the other one is metal fitting connection.
This is an analysis of the strength difference between these two methods.
Now, as a result of the analysis, Japan's construction technology is excellent, and strength can be ensured without the use of nails
,but it seems that it is no match for modern metal reinforcement.
If you think about it, ancient Japanese buildings are flexible structures that can be disassembled. Naturally, it is greatly deformed by shaking.
Therefore, the use of metal reinforcement is a necessary condition for ensuring safety.

もの凄く暇を持て余しているのでOpenFOAM等で遊んでいます.
今回は建築強度解析Vol01シュミレーションです。
PrePoMaxで柱と梁の接合方法による強度の違いを確認致しました。
柱と梁の接合には幾つかの種類があります。今回は日本古来のほぞ繋ぎ、もう一つは金具繋ぎで,この2方式による強度差の解析になります。
さて解析結果ですが、日本の建築技術は素晴らしく、釘などを使わなくとも強度確保が行われていますが、やはり近代的な金属補強には敵わないようですね。よく考えてみれば日本古来の建築物は分解が可能な柔構造。揺れによって大きく変形するのは当然なんですよね。従って金属製の補強材を使用することが安全確保のための必要条件になるのです。
注意事項: 基本的にOpenFOAMの解析条件(境界条件等々)は開示しておりません。
