Earthquake Resistant Mechanisms

What is the primary purpose of base isolation in earthquake-resistant buildings?

• To absorb moisture from the ground

• To reduce the energy transferred from the ground to the structure

• To increase the building's height

• To stabilize the foundation in waterlogged areas

Which material is commonly used in the construction of earthquake-resistant buildings for its flexibility and strength?

• Wood

• Concrete

• Steel

• Brick

What is the main function of shear walls in a building?

• To support the roof

• To allow more windows

• To resist lateral forces from wind and earthquakes

• To improve insulation

Damping systems in buildings are designed to:

• Increase the building's aesthetic appeal

• Absorb and dissipate seismic energy

• Decrease construction costs

• Increase the building's overall weight

What is a common characteristic of a moment-resisting frame?

• It is lightweight and temporary

• It allows columns and beams to bend without collapsing

• It is made entirely of wood

• It is designed for vertical loads only

Cross-bracing in a building helps to:

• Reduce the need for windows

• Increase the floor area

• Provide additional support against lateral forces

• Decrease the height of the building

What is the main advantage of using a tuned mass damper in a skyscraper?

• It reduces the need for maintenance

• It stabilizes the building against wind and seismic activity

• It adds extra floors to the building

• It eliminates the need for a deep foundation

Which of the following is an advantage of using a flexible diaphragm in building construction?

• It allows for greater insulation

• It distributes seismic forces more evenly
  

• It reduces construction time

• It increases the building's height

The concept of 'ductility' in earthquake-resistant design refers to a material's ability to:

• Conduct electricity

• Absorb moisture

• Undergo significant deformation without failure

• Reflect sound waves

Seismic retrofitting of existing buildings often includes the installation of:

• Solar panels

• Base isolators

• Roof gardens

• Elevator systems
