I have a lot of free time on my hands, so I've been playing with OpenFOAM and Blender and etc.
This is a simulation of Earthquake Vol03.
I used PrePoMax to check the earthquake resistance status of a house with an overhang on the second floor.
Instead of using the frequency like last time, I analyzed it using a method that shakes the ground horizontally.
A major earthquake occurred in Japan and Taiwan in early 2024.
In the previous Vol02, I confirmed the vulnerabilities due to differences in the foundation and structure of wooden buildings.
This time, I tried to confirm that even strong concrete buildings are vulnerable to design and irregular shapes.
One thing that Japan and Taiwan have in common is that their land is small. As a result, many buildings are designed to improve livability and usability.
Although these buildings offer a high degree of satisfaction in terms of livability and usability, it should be recognized that their safety against disasters such as earthquakes is extremely low.
I also performed dynamic analysis in parallel, but unfortunately it didn't turn out as expected! !

もの凄く暇を持て余しているのでOpenFOAM等で遊んでいます.
今回は地震Vol03のシュミレーションです。2階部分がオーバーハングした家屋の耐震状況をPrePoMaxで確認したのですが、
前回の様な周波数ではなく、地面を水平方向に揺らす方式で解析してみました。
2024年初頭に日本と台湾で大きな地震が発生しました。前回のVol02では木造建築の基礎と構造差による脆弱性の確認でしたが、
今回は強固なコンクリート建築であっても意匠性や異形による脆弱性の確認をおこなってみました。
日本と台湾の共通点の一つが狭い国土です。これにより居住性や利用性を高めるたデザインの建屋が多く存在しています。
これらの建屋は居住性や利用性の満足度は高くなりますが、地震などの災害に対する安全性が非常に低くなることを認識すべきですね。
動的解析も並行して行ったのですが想定通りに成らなず残念!!
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。
