What is a dangerous building? A dangerous building is one that has structural defects that could potentially affect the safety of its occupants or pedestrians nearby. According to our understanding, most dangerous buildings are older homes with long service life, as well as those damaged by natural disasters or human destruction. So, how can you determine if a building is dangerous? There is a standard for identifying dangerous buildings. Below, I'll discuss the methods for judging a building's danger, enabling you to quickly assess whether your property meets the criteria for a dangerous building.

I. Basic Standards

Independent column foundation is measured by the single basic unit of a single column; strip foundation is measured by the single face length of a natural room; full room red foundation is measured by the area of a single natural room.

1. Walls are measured by one story high and one side of a natural room.

2. Prefabricated panels are measured in blocks, cast panels by the area of a natural room.

3. Columns are measured by one layer high, one column per unit.

4. Beams, joists, rafters, etc., are measured by span and single piece.

5. Rafters are sold by the piece.

Section 2: Foundation, Basic Regulations

If the foundation should be sliding, or if the bearing level is not reached due to other reasons causing uneven settlement, which then leads to significant distortion, cracks, displacement, tilting, and other conditions with a tendency to worsen.

2. Basic aging, corrosion, and breakage, etc., have led to significant distortions, displacements, cracks, and tilts in the house structure, with a tendency for further deterioration.

3. Increased loads due to adjacent buildings' foundation proximity, or due to partial additional stories on its own, along with other human factors causing settlement, then leading to significant structural distortion, displacement, cracks, tilting, etc., and showing a tendency to worsen.
