## Question

What are the implications of settlement on structures?

## Short answer

Settlement causes cracking, tilting, structural distress, and damage to pipes and services. It leads to jamming doors, misaligned machinery, drainage issues, and reduced property value.

## Answer

Settlement of a foundation, if excessive or uneven, affects both appearance and safety of the structure.

- **Cracks** in walls, floors, beams and plaster from differential settlement.
- **Tilting** of tall structures such as towers and chimneys, as in the Leaning Tower of Pisa.
- **Extra stresses** in members of statically indeterminate frames, which can cause structural distress or even failure.
- **Damage to services:** pipes, drains, sewer lines and cables connected to the building may break.
- **Loss of serviceability:** doors and windows jam, floors slope, lifts and crane rails go out of line, and machinery loses alignment.
- **Drainage problems** and ponding around the structure.
- **Aesthetic and economic loss**, with costly repairs and a lower property value.

For this reason settlement is checked against permissible limits in addition to the bearing capacity check.

## Check yourself

The answer's key points as multiple-choice questions, with the correct option and why.

1. Which structures are most affected by tilting?
   A. Single-storey sheds
   B. Retaining walls only
   C. Pavements
   D. Tall structures such as towers and chimneys
   Answer: D. Pisa tower is the classic example. (Key point: Tilting)

2. What happens to statically indeterminate frames with differential settlement?
   A. Extra stresses develop in members
   B. No effect
   C. Moments vanish
   D. Loads shift to the soil only
   Answer: A. Support movement induces additional moments. (Key point: Indeterminate frames)

3. Why is settlement checked in addition to bearing capacity?
   A. Because bearing capacity is always unsafe
   B. Excess or uneven settlement harms serviceability and safety even when shear failure is not a risk
   C. Because settlement raises the water table
   D. Because it reduces the FOS to zero
   Answer: B. Settlement may govern the design. (Key point: Settlement check)
