2. What is the purpose of corner reinforcement in wall construction for earthquake resistance?
a) Enhancing aesthetic appeal
b) Providing additional structural support
c) Reducing material costs
d) Improving sound insulation
Answer: b) Providing additional structural support
Explanation: Corner reinforcement in wall construction strengthens the corners of buildings, which are vulnerable points during earthquakes. This additional support helps distribute seismic forces more effectively, reducing the risk of collapse.
3. Which structural elements are crucial for earthquake resistance in building construction?
a) Windows and doors
b) Roof tiles
c) Beams and columns
d) Interior decoration
Answer: c) Beams and columns
Explanation: Beams and columns play a vital role in distributing loads and resisting lateral forces during earthquakes. Proper design and construction of these elements are essential for ensuring the overall stability and earthquake resistance of a building.
4. What technique involves isolating a building from the ground motion during an earthquake?
a) Ground stiffening
b) Base isolation
c) Foundation reinforcement
d) Soil liquefaction
Answer: b) Base isolation
Explanation: Base isolation is a seismic protection technique that involves placing a building on flexible bearings or isolators to decouple it from the ground motion during an earthquake. This technique helps reduce the transfer of seismic forces to the building, thereby improving its earthquake resistance.
5. Which of the following materials is commonly used for base isolation in earthquake-resistant buildings?
a) Concrete
b) Steel
c) Rubber
d) Wood
Answer: c) Rubber
Explanation: Rubber bearings are commonly used for base isolation in earthquake-resistant buildings. These bearings provide flexibility and dampening properties, allowing the building to move independently of the ground motion during an earthquake.
6. How does base isolation contribute to earthquake resistance?
a) By increasing building height
b) By reducing building flexibility
c) By minimizing structural weight
d) By isolating the building from ground motion
Answer: d) By isolating the building from ground motion
Explanation: Base isolation techniques help mitigate the impact of seismic forces by isolating the building from ground motion. This isolation reduces the transmission of seismic energy to the structure, enhancing its earthquake resistance.
7. What is the primary function of earthquake-resistant building design?
a) Maximizing architectural complexity
b) Minimizing construction costs
c) Enhancing structural integrity
d) Expediting construction timelines
Answer: c) Enhancing structural integrity
Explanation: The primary function of earthquake-resistant building design is to enhance structural integrity by incorporating features and techniques that improve the building’s ability to withstand seismic forces, ensuring the safety of occupants during earthquakes.
8. Which aspect of construction is essential for ensuring earthquake-resistant buildings?
a) Rapid construction techniques
b) Use of lightweight materials
c) Compliance with building codes

9. How does corner reinforcement contribute to earthquake resistance in building construction?
a) By increasing architectural complexity
b) By enhancing structural stability
c) By reducing material costs
d) By providing additional support
Answer: d) By providing additional support
Explanation: Corner reinforcement in building construction helps strengthen vulnerable points, reducing the risk of collapse during earthquakes. This additional support enhances the overall structural stability and earthquake resistance of the building.
10. What role do beams play in earthquake-resistant building construction?
a) Supporting interior decorations
b) Enhancing sound insulation
c) Distributing loads and resisting lateral forces
d) Improving natural lighting
Answer: c) Distributing loads and resisting lateral forces
