The Artificial Earthquakes

For the competition, all the models will be tested on the shaking-table for different sized earthquakes. We will start with a very small earthquake. Then we will gradually increase the size of the earthquakes to the maximum the shaking-table can produce.

We will make a note of the mass of your model and the size of the earthquake that caused its failure.

Your model will be judged to have failed when any of the following things have happened to it:

• Complete collapse of the model.
• Collapse of one or more storeys.
• The model has deformed excessively.
• There has been extreme damage to your model.
• If any of the steel blocks on your model (see At Bristol Rules for Vertical Loading ) fall through the floors.
• If any of the steel blocks fall out of the model as a result of damage to the model. However, if they fall out because we did not glue them in place properly (see At Bristol Rules for Vertical Loading), the blocks will be replaced and re-glued.
