Apartment Block, Tung Shih
frame of this apartment block was constructed from reinforced
concrete. The ground floor storey
of the building collapsed because the columns
at that level failed.
You can see that there was neither bracing
between the columns, nor any walls as in the storeys above.
If there had been, they would have helped resist the sideways
sway caused by the earthquake.
This type of failure is called a soft-storey
failure. The earthquake caused many failures of this type.
