3. Do you know what is a
skyscraper???
A very tall building with many storeys.
Tall structures whose height is much larger and are
qualitatively different in construction from smaller
ones.
The steel frame, the elevator, the telephone, and
the revolving door are all key to their invention
They appeared first at time of 19th century
4. History of skyscraper
The increase of the high of buildings
was a big step for the construction
industry and come together with the
technological development.
water pressure was usually
insufficient to supply running water
above 50 m.
5. Which place is called as the
World’s oldest man-made
skyscraper ?????
The Great Pyramid of Giza was the tallest manmade structure in the world for nearly 4,000 years...

9. First skyscraper
The first skyscraper was the
ten-storey Home Insurance
Building in Chicago, built in
1884–1985.
In this building, a steel frame
supported the entire weight of
the walls,instead of loadbearing walls carrying the
weight of the building, which
was the usual method.
12. What is Green Skyscraper ?
Benefits and impacts have been studied in
terms of energy savings and indoor
environmental qualities.
For example green roof can reduce 50% of
cooling load; green wall can reduce 10 degree
centigrade indoor temperature, where as
biofilter and indoor plants purifies indoor air by
50% to 60%.
14. Materials used to built
skyscrapers
At first, air was injected into molten steel to
reduce the impurities, and increase the
temperature of the steel
Later, carbon and manganese were added to
improved the strength, and eliminate the
effects of other impurities, mainly sulfur
High volume, cheap, strong steel was the result
15. Raw Materials
Reinforced concrete is one important
component of skyscrapers.
Concrete is inherently strong under
compressive forces.
This high-strength material was achieved
by adding very fine particles to the usual
concrete ingredient
16. Upcoming skyscrapers
Before considering the technical
hurdles of constructing tall
buildings from wood, perhaps the
which should be as the specific
benefits wood can offer over
concrete and steel?
17. Architectural
companies are
beginning to wake up
to the promise of
wooden tall buildings,
and Swedish firm Berg
C.F. Møller is just one
recent example of this.
The company has
proposed a 34-story
wooden skyscraper for
HSB Stockholm's
architectural
competition.
