What can keep a simple structure from collapsing during an earthquake?
How will an earthquake, simulated by shaking, affect a "building" made of linked squares? How can the square "stories" be cross-braced to prevent the "walls" from collapsing? What dangers are there in building above a garage?..
For Testing Structures Built in Earthquake Country
Building in earthquake country can be a tricky business. Architects and engineers run simulations using models and shake tables to test the integrity of buildings and determine necessary reinforcements. In this activity, students use a very simpl..
