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

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
