Q
Functional Requirements
7
A
- Strength
- Stability
- Damp and gas resistant
- Durability
- Fire Saftey
- Thermal Insulation
- Sound Insulation
5
Q
Strength
A
- Must be strong enough to resist dead and imposed forces
- Based on materials used
- For small loads and small spans timbre can be used
- Precast concrete block used as a timbre alternative
- For large spans and large loads reinforced concrete and steel floors are used
6
Q
Stability
A
- Adequate stiffness to remain stable under load
- Should suport serveices without compromising stability
- Diflection under load should be kept to minimum to avoid cracking rigid fixtures
7
Q
Damp resistance
A
- Resist passage of moisture thtoguh ground floors to inside of the building
- DPM
8
Q
Durability
A
- Durability for expected lifespan of building
- Should require little miantenance
- Durability of finishes depends on materials and environmental exposure
9
Q
Fire Saftey
A
- Upper floors should provide resistance for adequate period of evacuation
- TIme period between 30mins and 4Hrs depending on size and function of the building
10
Q
Thermal Insulation
A
- Should provide resistance to heat transfer, when there is a difference in air temperatures on opposite sides of a floor
11
Q
Sound Insulation
A
- Upper floors that separate dwellings should proof the transfer of sound
12
