Scaled down models of structures, such as dams,
bridges and buildings, are made in the EERC
laboratory to be tested for simulated earthquakes (Why?).
They are mounted on the EPSRC
shaking-table (Show Me),
a large testing machine for generating earthquakes.
The shaking-table is a 3 metre square aluminium platform
which is made to move using hydraulic-actuators.
It is controlled by computers (Show
Me), and can move sideways, up and down and even rotate.
In the picture of the model building, (See
close up) you can see that weights have been added
to each floor. (Why?)
