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 Vol02.
Most ordinary houses in Japan, a country prone to earthquakes, are constructed of wood, and the level of earthquake resistance varies depending on the year of construction.
Therefore, this time I used PrePoMax to check the differences in seismic resistance depending on the foundation of the house.
Without any analysis, it is clear that the stronger the structure of a house, the more seismic strength it will have, but I have tried to visually express the importance of the foundation.
Since around 2010, the number of new one-story houses has been increasing in Japan, but in Japan, which has a small land area, two-story houses seem to be more common.
It is clear from analysis that houses with insufficient earthquake resistance measures and old foundations are extremely fragile, so even if they are sufficiently earthquake resistant,
heavy objects should not be moved to high floors such as the second floor.
My learning of PrePoMax frequency analysis is insufficient. Also note that the display highlights the results in advance.

Note: Basically, I don't disclose the analysis conditions (boundary conditions, etc.) of OpenFOAM

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Vol02のシュミレーションです。地震多発国日本の一般家屋の殆んどが木造建築、また建築年代により耐震レベルにも差があります。
そこで今回は家屋基礎の違いによる耐震状況の差をPrePoMaxで確認してみました。
解析するまでなく家屋の構造が堅牢であるほど耐震強度が増すことは明らかですが、基礎の重要性を視覚的に表せてみました。
2010年頃から日本では平屋の新築数が増加の傾向にあるようですが、それでも国土面積の狭い日本では2階建て家屋が多い傾向にあります。
耐震対策が十分で無く、且つ古いタイプの基礎を持つ家屋は非常に脆弱な状態であることが解析でも明らかで、仮に耐震が十分に施されていても、
重量物を2階などの高い階に置かない方が賢明です。
私はPrePoMaxの周波数解析の習得が不十分です。また表示は結果を強調表示していることを予め。
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。
