The lesson was started with planning the location of infrastructure in
earthquake area. Then discussion was started about the reasons for the collapse
of infrastructure is poor design.To avoid such situation earthquake resistant
buildings are added to new infrastructure.
To be earthquake proof, buildings, structures and their foundations need
to be built to be resistant to sideways loads. The lighter the building is, the
less the loads. This is particularly so when the weight is higher up. Where
possible the roof should be of light-weight material. If there are floors and
walls and partitions, the lighter these are the better, too. If the sideways
resistance is to be obtained from walls, these walls must go equally in both
directions. They must be strong enough to take the loads. They must be tied in
to any framing, and reinforced to take load in their weakest direction. They
must not fall apart and must remain in place after the worst shock waves so as
to retain strength for the after shocks.
Explaination about new infrastructure designs make use of
latest technology to help structures with stands the force of an earthquake was
done. Students were explained about about the steel bars are used to strengthen
new infrastructure so that they are better equipped to withstand earthquake, In
addition, shock absorbers are used in the foundation to help absorb the tremors
of earthquake Shear walls the concrete walls with steel bars in them act
as support walls to strengthen the
building and help to reduce the rocking movements caused by an earthquake.
Although this it
is expensive to construct such kind of infrastructure, but some countries are
coming up with this construction to avoid number of deaths because of poor
infrastructure. examples San Francisco
has used it on Transamerica pyramid.
