Firstly, Earthquake resistant buildings should have  Cross-bracing , shear walls and shock absorbers/base insulators.  ]]> 2016-07-31 11:04:22 UTC https://padlet.com/joellim_cz/pt9o3b3i87p4/wish/117239564 catangel https://padlet.com/joellim_cz/pt9o3b3i87p4/wish/117239684 Cross-bracing is to reinforce walls by using two steel beams. ]]> 2016-07-31 11:15:47 UTC https://padlet.com/joellim_cz/pt9o3b3i87p4/wish/117239684 catangel https://padlet.com/joellim_cz/pt9o3b3i87p4/wish/117239697 Shear walls are concrete walls with steel bars in them to reduce rocking movements]]> 2016-07-31 11:16:36 UTC https://padlet.com/joellim_cz/pt9o3b3i87p4/wish/117239697 catangel https://padlet.com/joellim_cz/pt9o3b3i87p4/wish/117239705 Shock absorbers absorb the tremors of the earthquake.]]> 2016-07-31 11:17:40 UTC https://padlet.com/joellim_cz/pt9o3b3i87p4/wish/117239705 catangel https://padlet.com/joellim_cz/pt9o3b3i87p4/wish/117239730 An example would be the Transamerica Pyramid in San Francisco which costed $75 Million to build.]]> 2016-07-31 11:18:44 UTC https://padlet.com/joellim_cz/pt9o3b3i87p4/wish/117239730 catangel https://padlet.com/joellim_cz/pt9o3b3i87p4/wish/117239857 2016-07-31 11:26:56 UTC https://padlet.com/joellim_cz/pt9o3b3i87p4/wish/117239857 catangel https://padlet.com/joellim_cz/pt9o3b3i87p4/wish/117240133 A limitation on these new buildings are that there are still many people who are not economically stable to live in the buildings.
