Possible problems are tilting into adjacent
building, aesthetic - eye very sensitive to
tilting (1:100), rolling, tilting of bridge piers.
Tilting may also overload foundation
causing a BCfailure.

Damage
Category
(1)
Description of typical damage
(2)
Negligible Hairline cracks < 0.1 mm < 3 cm < 1/300
Very Slight
Very slight damage includes fine cracks
that can be easily treated during normal
decoration, perhaps an isolated slight
fracture in building, and cracks in external
brickwork visible on close inspection
1 mm 3 cm ~ 4 cm 1/300 to 1/240
Slight
Slight damage includes cracks that can
be easily filled and redecoration would
probably be required; several slight
fractures
may appear showing on the inside of the
building; cracks that are visible externally
and some repointing may be required;
doors and windows may stick
3 mm 4 cm ~ 5 cm 1/240 to 1/175
5 mm to 15 mm 5 cm ~ 8 cm 1/175 to 1/120
or a
number
of craks
> 3 mm
15 mm to 25 mm 8 cm ~ 13 cm 1/120 to 1/70
but also
depends on
number of
craks
Usually
>5 mm > 13 cm > 1/70
but also
depends on
number of
craks
Notes
1 . : Maximum differential settlement of the foundation
2. /L : Maximum angular distortion of the foundation
Very severe
Very severe damage often requires a major
repair job involving partial or complete
rebuilding; beams lose bearing; walls lean
and require shoring; windows are broken
with distortion; there is danger of structural
instability
Moderate
Moderate damage includes cracks that
require some opening up and can be
patched by a mason; recurrent cracks thatcan be masked by suitable linings;
repointing of external brickwork and
possibly a small amount of brickwork
replacement may be required; doors and
windows stick; service pipes may fracture;
weathertightness is often impaired
Severe
Severe damage includes large cracks
requiring extensive repair work involving
breaking out and replacing sections of
wall (especially over doors and windows);
distorted windows and door frames;
noticeably sloping floors; leaning or
bulging
walls; some loss of bearing in beams;
disrupted service pipes
