41.21. Base Isolation and Seismic Dampers

Try these first

1. 1.

   What is the primary purpose of base isolation?

   Hint

   Think about how a building can be separated from ground motion.

2. 2.

   Name one type of seismic damper.

   Hint

   Recall the different types of devices that absorb seismic energy.

3. 3.

   What is the goal of base isolation in seismic design?

   • To completely eliminate all shaking
   • To reduce the energy transferred to the structure
   • To make buildings heavier

   Hint

   Consider what base isolation is designed to achieve.

4. 4.

   True or False: Seismic dampers can only be used in new constructions.

   • True
   • False

   Hint

   Think about buildings that are already built.

5. 5.

   Design an earthquake-resistant structure using both base isolation and seismic dampers. Provide the specifications of the building, the type of base isolation system, and the dampers to be installed.

   Hint

   Consider the building's height, usage, and local seismic codes.

6. 6.

   Evaluate the effectiveness of various types of seismic dampers based on a given scenario of earthquake impact. Which would be most suitable and why?

   Hint

   Focus on the building's area and expected movement.
