What is HIGH RISE building . . . ?
• Basic Definition- A high-rise building is defined as a building 35 meters or greater in height, which is divided at regular
intervals into occupiable levels. To be considered a high-rise building an edifice must be based on solid ground, and
fabricated along its full height through deliberate processes (as opposed to naturally-occurring formations
• PRIMARY DEFINITION
Primary definition–the word ‘high' means– extending up words or elevated . and rise means – the act of rising or
advance. -So high - rise means the act of rising to extending up words
Defined by–
which structure might have reached up to 10 or more stories and having 200 storied called high–rise.
-ancient roman law.
a high–rises being higher then70 feet.
-United states general laws
a high – rise building is one with four floors or more ,or one 15 meters or more in height.
-code of Hyderabad, India.

Skyscraper
CHARACTERISTICS
1.A skyscraper is a tall, continuously habitable building having multiple floors.
one of at least 40-50 floors.
2. Mostly designed for office, commercial and residential uses a skyscraper can
also be called a high-rise.
3. skyscrapers is having a steel framework that supports curtain walls.

SUPERTALLS are a special class of skyscraper. More expensive to build than
shorter structures, they require special wind-tunnel and seismic analysis, stiffer
frames, extra material and special elevators, and often refuge floors or other safety
measures.

An emergency exit in a structure is a special exit for emergencies
such as a fire: the combined use of regular and special exits
allows for faster evacuation, while it also provides an alternative
if the route to the regular exit is blocked by fire, etc. It is usually a
strategically located outward opening door with a crash bar on it
and with exit signs leading to it.

•Can not use sliding and hanging door
•Exit door must be open towards the

2 exits will be used
If the number of user is 1000

STAIRS – Used for stepper
slopes can be a lot of deferent
forms like spiral , monumental

ESCALATOR – Used for a
lot of people and moving
the stairway, give a
continuous floor either up or
down.
ELEVATOR –
This is the best method
to create
a easy vertical
circulation when
a lot of people can
use it.

Elevator
An elevator or lift is a type of vertical transport equipment that efficiently moves people or goods
between floors of a building or other structures. Elevator are generally powered by electric motors
that either drive traction cables or counterweight system likes a hoist, or pump hydraulic fluid to
raise a cylindrical piston like jack.

Being the oldest system in building construction, the post and lintel system
is the first man made architectural process of construction. Post lintel is a
simple construction technique where a horizontal member (lintel)is
supported by two vertical posts at either end.

ADVANTAGE
 EARTHQUAKE RESISTANCE IS BETTER THAN ANY
OTHER SYSTEM.
 GRADE BEAM PROVIDES EXTRA SAFETY.
 DIFFERENTIAL SETTLEMENT DOES NOT OCCUR.
 MORE FLEXIBILITY IN ARRANGEMENT OF SPACE.
 IN CASE OF HIGH RISE BUILDINGS,STRUCTURAL
DESIGN IS EASY.
 WALLS CAN BE PLACED ANY WHERE.
 SLAB THICKNESS LESS THAN THAT OF FLAT-SLAB.
DISADVANTAGE
 LESS OPEN SPACE COMPARED TO THE OTHER
STRUCTURAL SYSTEMS.
 BEAMS AFFECT THE APPEARANCE OF THE OPEN
SPACES GREATLY.
 MORE MATERIAL AND TIME NEEDED FOR
CONSTRUCTION.
 SPANS ARE USUALLY LESS, VAULTS WAFFLE SLAB
AND DOMES TEND TO REDUCE IT MORE.

General information
The bank of china is located at
garden road and was finished in
1990.
This building is used for banking and
has offices. This is made out of glass
and metal.
It was designed by I.M.pei. It is

diagonal tower
64-storey Diagonal Tower to be located in the
developing commercial and mixed-use in the heart
of Seoul, South Korea, exudes a modern take on
structural expressionism.
Rising to 343 meters, the diagonal structure
serves more than visual stimuli. Somewhat
similar to Norman Foster’s Hearst Towerin New
York, the diagonal megaframe reduces the
amount of steel required by over 25% when
compared to conventionally framed buildings. In
addition the non-linear vertical surface mitigates
wind loading and vortices. Primary structural
support is achieved via 4 piers at the corners of
the building – which in turn opens up the interior
lobby and atrium.
