What is the maximum height allowed for a masonry pier used in a seismic zone?

1. No. 9 (m# 32)

2. No. 10 (m# 34)

3. No. 11 (m# 36)

4. No. 12 (m# 38)

The correct answer is: No. 11 (m# 36)

The correct choice signifies that the maximum height allowed for a masonry pier utilized in a seismic zone is 11 feet, which correlates with the guidelines established for construction in areas prone to seismic activity. This height restriction is crucial to ensure stability and resilience against the forces generated by potential earthquakes. Masonry piers serve as vertical structural elements that need to possess significant strength and durability, especially in regions where seismic events can lead to additional lateral loads on structures. The specified height of 11 feet ensures that piers can effectively support the loads imposed on them without compromising safety or structural integrity. Understanding this height limitation is integral for builders and contractors operating in seismic zones to comply with building codes and regulations designed to safeguard structures and their occupants. Such guidelines help in mitigating risks associated with seismic activities, ensuring that construction practices align with safety standards expected in these vulnerable areas.
