Its name is derived from "Empire State",
the nickname of the state of New York. It stood
as the world's tallest building until 1970
(World Trade Center). its collapse in
the September 11, 2001 attacks, the Empire
State Building was again the city's tallest
skyscraper until 2012. As of 2020, the building
is the seventh-tallest building in New York
City, the ninth-tallest completed skyscraper
in the United States, the 48th-tallest in the
world, and the fifth-tallest freestanding
structure in the Americas.

4. Site
The site of the Empire State Building,
located in Midtown South on the west side
of Fifth Avenue between
West 33rd and 34th Streets, was originally
part of an early 18th-century farm.
It was developed in 1893 as the site of
the Waldorf–Astoria Hotel. In 1929,
Empire State Inc. acquired the site
and devised plans for a skyscraper
there. The design for the Empire State
Building was changed fifteen times
until it was ensured to be the world's
tallest building.

5. Lamb produced the building
drawings in just two weeks using the
firm's earlier designs as the
basis. The 1916 Zoning Act forced
Lamb to design a structure that
incorporated setbacks resulting in
the lower floors being larger than
the upper floors. Consequently, the
tower was designed from the top
down, giving it a "pencil"-like
shape.

6. The Structure of the tower is braced steel frame with semi-
rigid connections. It remains stiffest of the tower for its
height, due to largely due to heavy cladding that is designed
to stiffen the frame.
Single core system The system structure of a tall building with a centre
single core (single core) and within short columns (mullion) which bear
the floor with the core of the building.
 The core of the building except bears the vertical load is also
burdened with a horizontal force due to the earthquake and wind.
 There are windows on four sides providing excellent light and views.
Shear Walls: To resist the lateral load caused
by wind and Earthquake
 The Assembly of shear wall is known as
“Coupled Shear Wall”
 Belt Trusses distribute the tensile and
compressive force to the large no of
exterior truss.

7. The building's Art Deco architecture, height, and observation decks have made it a popular
attraction. Around 4 million tourists from around the world annually visit the building's 86th
and 102nd floor observatories; an additional indoor observatory on the 80th floor opened in
2019.

8. The Empire State Building is an American cultural icon.
A symbol of New York City, the tower has been named as
one of the Seven Wonders of the Modern World by
the American Society of Civil Engineers. It was ranked first
on the American Institute of Architects' List of America's
Favorite Architecture in 2007. Additionally, the Empire
State Building and its ground-floor interior were
designated city landmarks by the New York City
Landmarks Preservation Commission in 1980, and were
added to the National Register of Historic Places as
a National Historic Landmark in 1986.

9. Plans

12. The original plan of the building was 50 stories, but
was later increased to 60 and then 80 stories . Height
restrictions were placed on nearby buildings to
ensure that the top fifty floors of the planned 80-
story, 1,000-foot-tall (300 m) building would have
unobstructed views of the city.
While plans for the Empire State Building were
being finalized, an intense competition in New York
for the title of "world's tallest building" was
underway. The plans included an observation deck
on the 86th-floor roof at a height of 1,050 feet
(320 m), higher than the Chrysler's 71st-floor
observation deck.
The roof height was now 1,250 feet (380 m),
making it the tallest building in the world by far,
even without the antenna. The addition of the
dirigible station meant that another floor, The
final plan was announced to the public on January
8, 1930, just before the start of construction.

from the 86th floor ticket offices to a 33-foot-wide 101st-
floor waiting room. From there, stairs would lead to the
102nd floor. Total Lifts/elevators are 73. Visitors reach the
86th Floor Observatory by elevator in less than one
minute.

The exterior of the Empire State Building is
