ICT science: Forces and Structures:
In science
class, we are learning about different forces and structures as a new unit. We
started watching videos of construction of really tall buildings. The video we
were watching was about the building of the shanghai world financial center in
China. It was a building that was for offices, apartments, hotels, and
restaurants, and this building was just under 500 meters tall, and had a circle
constructed at the top, but was later changed to a trapezoid. Also, when it was
constructed, every 12 floors, there was a safe floor area for people to stay in
case of a fire, or any other problem. When workers started
constructing the building, they had to make sure it would be firmly stuck on
the ground to prevent it from swerving side to side in case of a windy storm,
so they had to add supports. The workers had to first install giant metal rods
in the ground connected to the building to keep it stand strait and to put
concrete with metal rods lying within the structure. The top trapezoid was to
let wind through so it would resist moving, and also for
the decoration. In science class we are
about to do a project on one big structure and do research on it, and I am very
excited for it.
