How do I make a earthquake proof building?
In science we are learing about earthquake proof buildings. And I have to make an earthquake proof building out of pasta. What is that best way to do so? Is there a special way that I should make it..like the base or how the pasta is glued together. Thanx so much!!! I really want to get an A!
Try something with a lot of diagonals.

All buildings with right angles have easily excitable mechanical resonances at relatively low frequencies.
Especially shear modes where one floor moves parallel to another lead to knocked out walls and the buildings collapse easily. The angled walls will transfer the motion from the lower floors to the upper floors better and the whole building is more likely to move in one direction. This limits the amount of shear forces on walls. Since the walls are already designed to hold up under an angle other than vertical (box buildings are usually nothing but a heavy house of cards… once a wall leans… it falls!) it is much harder to push the walls over.
Structures which have these diagonals are also much stiffer and the resonance frequencies are past the range of excitations during an earthquake. The result is that less energy gets transfered into the building and the structure are far more likely to survive without any major damage.
