Objectives/Goals
The purpose of our project was to find out what
shaped structure resisted earthquakes most successfully.
Methods/Materials
First we built a shake table using plywood, springs,
a small motor, and batteries. Next we built structures in the shapes of L, T,
U, and square out of sugar cubes and peanut butter. We then tested the
structures on our shake table. We graphed the data and prepared our backboard
and report.
Results
The square-shaped structure withstood the simulated
earthquake most successfully. The t-shaped structure performed the worst. The
L-shaped collapsed from top to bottom, leaving a pyramid-type ruin standing.
The U-shaped building failed at the bend, falling outward. The T-shaped
building interestingly was the only structure to collapse inward.
The square structure seemed to take the shaking
force and distribute it equally throughout the building, making the structure
more resilient to the shaking.
Conclusions/Discussion
Our hypothesis was that the square shaped structure
would perform the best in a simulated earthquake.
The results indicate that this hypothesis was
correct.
Project Summary
By using a shake table, we determined which shaped
structure could withstand an earthquake most successfully.
