Foundation Types and Bearing Capacity Quiz

What is the main function of a structural foundation?

• To prevent water accumulation

• To support the roof structure

• To channel or transmit the building load to the earth

• To provide aesthetic appeal to the building

Which type of foundation is used to spread out building column and wall loads?

• Floating foundation

• Spread (pad) footings

• Mat foundation

• Deep foundation

What is a mat or raft foundation?

• A foundation made of wood

• A type of floating foundation

• A large footing extending over a large area

• A foundation that only supports walls

What is a floating foundation primarily used for?

• In areas with solid rock

• For small residential buildings

• In regions with high seismic activity

• Under specific conditions with compressible cohesive soil

What defines a shallow foundation?

• Depth greater than the width of the foundation

• Depth less than or equal to the width of the foundation

• Only used for residential buildings

• Requires deep excavation

Which factor is NOT important when considering shallow foundations?

• Location and depth of foundation

• Function of the structure

• Aesthetic design of the building

• Subsoil condition

What is the ultimate bearing capacity of soil?

• The weight of the building

• The type of soil used

• The maximum load a foundation can support

• The depth of the foundation

What does the net ultimate bearing capacity (qnu) represent?

• The type of foundation used
