Build a Better wall is an activity for students to help with earthquake mitigation.
This activity helps students learn how diagonal braces, shear walls, and rigid connections strengthen a structure to carry forces resulting from earthquake shaking. It can be done as a demonstration, or as group projects in a classroom. It takes preparation to assemble and drill the parts, but worth it for a permanent classroom tool.
Developed by FEMA for their "Seismic Sleuths" instructional booklet. Additional "Earthquake Safety at Home" . Additional safety information is available on their website: http://www.fema.gov/earthquake-safety-home.
Two additional activities on "base isolation" are included to learn more about protecting large structures.
This activity is a good bridge between the "Earthquake Machine" and the "BOSS Model".
- Learn the structural elements of a building
- Describe how the structural elements carry the horizontal and vertical loads
- Describe the use of diagonal braces and shear walls
- Learn about base isolation for tall buildings
