What is the maximum height of a masonry pier when used in a seismic zone?

1. 8 feet

2. 10 feet

3. 11 feet

4. 12 feet

The correct answer is: 11 feet

The correct answer is 11 feet. In seismic zones, building codes often have specific requirements to ensure the structural integrity and safety of buildings during seismic events. Masonry piers are essential components in supporting structures, and their height is limited to mitigate the risk of failure in the event of an earthquake. The determination of the maximum height takes into account several factors, including the material strength and the forces that a pier must withstand during seismic activity. An 11-foot height provides a balance between structural support and risk management, ensuring that the pier is not excessively tall, which could increase the likelihood of collapse or instability. The maximum height limits are established to maintain code compliance, aiming for safety and resilience in buildings situated in areas prone to seismic activity. Understanding these specifications is crucial for contractors and builders to ensure the safety of their structures and compliance with local building codes.
