Watching the news only increases my frustration.
Whoever did this?
Reinforced steel frame for destroyed columns in Pohang.
Steel + Jack? Problems.
1.철골은 H형의 아이자 빔을 썼다
In the steel frame, the part receiving the force is the flange part.
In other words, the short end plates on both sides receive strength
The iron plate in the middle (wave) has a different amount of power (differs the purpose of power)
To make the steel frame receive strength
So that both ends of the flanges receive the force
A thick steel plate at the end of the steel frame
It receives the strength properly. .
2.잭의 설치불량.
Jack's position is on the wave
Not receiving strength (about 1/100th)
Above all, the installation of the jack
Through a thick steel plate at the end of the steel frame
Two or more must be installed to receive power. .
3천정 부분에는
There is a ceiling frame called m-bar
This is a stumbling block to receiving power.
In other words, it must have been removed, and the ceiling side
Reinforced steel plate is required to receive strength. .
4.용접부를 보면
Welding is also bad.
Dotted welding like that
I can't get that power.
Comprehensively
지금 철골 보강해놓은것은? “눈속임”이다. ?부실이 또다른 부실을 만들고있다.
If you have learned architectural mechanics
I wouldn't have done that.
If you don’t know, ask a building structure engineer
Even if I had only consulted, it would have been easy.
