Transcript of Earthquake Engineering
bad things happened...
people came up with ingenious ideas.....
How can we expand?
there isn't enough space...
Put more people in less space!
people died :(
some buildings even sank!
they are more effective than mortar walls in many cases
they were extensively used by the Incas - many of them are still standing
the Incas built using this method In Peru, a very earthquake-prone country

dampening device fitted onto supports / foundations
made from a lead core and rubber outer rings
these are enormous counterweights mounted inside buildings
they counteract the swaying of the skyscraper
we can utilise simple shapes to make buildings far stronger
we get great stability and strength from these shapes
this helps to reduce resonance
work in very much the same way as LRBs
move laterally to absorb shock and movement
relatively easy to use
placed in strategic points around foundations
