This document discusses the demand for and development of high-rise buildings. It defines high-rises as buildings between 35-100 meters tall or having 12-39 floors. Over time, demand has increased due to factors like scarcity of land and technological advances enabling taller structures. Structural systems have also evolved from bearing walls to more sophisticated exterior tube and outrigger designs that allow for greater heights. The core, composed of elevators and other services, plays an important role in resisting lateral wind loads. Modern skyscrapers often use tube systems that move columns to the perimeter, creating a hollow rigid structure.

Book Formatting: Quality Control Checks for DesignersConfidence Ago
This presentation was made to help designers who work in publishing houses or format books for printing ensure quality.
Quality control is vital to every industry. This is why every department in a company need create a method they use in ensuring quality. This, perhaps, will not only improve the quality of products and bring errors to the barest minimum, but take it to a near perfect finish.
It is beyond a moot point that a good book will somewhat be judged by its cover, but the content of the book remains king. No matter how beautiful the cover, if the quality of writing or presentation is off, that will be a reason for readers not to come back to the book or recommend it.
So, this presentation points designers to some important things that may be missed by an editor that they could eventually discover and call the attention of the editor.

S
First Generation1780-1850
⮚ The exterior walls of these buildings consisted of stone or
brick, although sometimes cast iron was added for decorative
purposes.
⮚ The columns were constructed of cast iron, often
unprotected; steel and wrought iron was used for the beams;
and the floors were made of wood.

and the floors were made of wood.
Second Generation 1850-1940
⮚ The second generation of tall buildings, which includes the
Metropolitan Life Building (1909), the Woolworth Building
(1913), and the Empire State Building (1931), are frame
structures, in which a skeleton of welded- or riveted-steel
columns and beams, often encased in concrete, runs through
the entire building.
⮚ This type of construction makes for an extremely strong
structure, but not such attractive floor space. The interiors are
full of heavy, load-bearing columns and walls

7. DEVELOPMENT OF STRUCTURAL SYSTEMS
Third Generation 1940-present
⮚ Buildings constructed from after World War II
until today make up the most recent
generation of high-rise buildings.
⮚ Within this generation there are those of steel-
framed construction( core construction and
tube construction ), reinforced concrete
tube construction ), reinforced concrete
construction(shear wall), and steel-framed
reinforced concrete construction .
⮚ Hybrid systems also evolved during this time.
These systems make use more than one type of
structural system in a building.

9. TALL BUILDING TRENDS IN 2013
Considering the worlds 100 tallest buildings in 1990:
◻ 80 percent were located in North America.
◻ Almost 90 percent were exclusively office use.
◻ More than half were constructed of steel.
◻
In 2013, for the world's 100 tallest buildings:
◻ The largest share (43 percent) are now in Asia. (Only one
new 200-m-plus building was built in North America in
2013, compared to 54 in Asia.)
◻ Less than 50 percent are exclusively office use. Almost
a quarter are mixed-use and 14 percent are residential.
◻ Almost half were constructed of reinforced concrete and
only 14 percent of steel. (The remaining are composite or
mixed structural materials.)
10. TALL BUILDING TRENDS IN 2013
A composite tall
building utilizes a
combination of both
steel and concrete
acting compositely in the
main structural elements.
A mixed—structure tall
building is any building
that utilizes distinct steel
or concrete systems
above or below each
other.

11. STRUCTURAL CONCERNS
◻ The primary structural skeleton of a tall building can be visualized as a
vertical cantilever beam with its base fixed in the ground. The structure has
to carry the vertical gravity loads and the lateral wind and earthquake loads.
◻ Gravity loads are caused by dead and live loads. Lateral loads tend to snap
the building or topple it. The building must therefore have adequate shear
and bending resistance and must not lose its vertical load-carrying capability.
The skyscraper pushes down on into the ground
.But when the wind blows, the columns in the
windy side stretch apart, and the columns on the
other side squeeze together.

13. LOAD DISTRIBUTION SYSTEM :
All type of loads can be considered
as_
• Vertical load &
• Lateral load
Vertical loads transfer through_
• Bearing wall
• Column
• Column
• Core
• Diagonal frame

• Shear wall
• Slab
• Beam
• Diagonal Frame
14. Structural member:
Beam :
Beam is a rigid structural member designed to carry
and transfer loads across spaces to supporting
elements.
Column :
A rigid relativity slender structural member designed
primarily to support axial compressive loads
applied at the member ends.
In high rise buildings it can be use as mega column,
In high rise buildings it can be use as mega column,
concrete filled tubular(CFT) etc.
Shear wall:
A vertical diaphragm or wall acting as a thin, deep
cantilever beam in loads to the ground foundation.
Bracing :
It is a structural element for positioning,
supporting, strengthening or restraining the
member of a structural frame.
15. Core :
Core is one of the most important structural and
functional elements of the high rise building.
The core of a building is the area reserved for elevators’ stairs,
mechanical equipments and the vertical shafts that are
necessary for ducts, pipes and wires.
Its wall are also the most common location for the vertical
wind bracing.
The placement of the service core stems from four generic types
which are :
which are :
- Central core
- Split core
- End core
- Atrium core

Structural typology:
According to ‘Council on Tall Buildings and Urban habitat’ there are four
types
of structural system-
According to Mir M. Ali and Kyoung Sun Moon, Structural systems of tall
buildings can be divided into two broad categories-
1.interior structures and
2.exterior structures.
According to material it can be also-
1. Concrete type and
2. steel type
17. INTERIOR STRUCTURES
By clustering steel columns and beams in the core, engineers create a stiff backbone that can resist
tremendous wind forces. The inner core is used as an elevator shaft , and the design allows lots of open
space on each floor
Interior structure
1. Rigid Frames
2. Shear Wall Hinged Frames
3.Shear Wall (or Shear Truss) - Frame Interaction System
4. Outrigger Structures
Interior and exterior classification is based on the distribution of the components of the
primary lateral load-resisting system over the building.
4. Outrigger Structures
EXTERIOR STRUCTURES
In newer skyscrapers, like the Sears Tower in Chicago, engineers moved the columns and beams from
the core to the perimeter, creating a hollow, rigid tube as strong as the core design, but weighing much,
much less.
Exterior structure
1. Tube
2. Diagrid
3. Space Truss Structures
4. Super frames
5. Exo-skeleton

engineers create a stiff backbone that can resist tremendous
wind forces. The inner core is used as an elevator shaft , and
the design allows lots of open space on each floor

20. INTERIOR STRUCTURAL SYSTEM
1)RIGID FRAME
◻ A rigid frame in structural engineering is the load-
resisting skeleton constructed with straight or curved
members interconnected by mostly rigid connections
which resist movements induced at the joints of
members. Its members can take bending moment,
shear, and axial loads.
◻ Consist of columns and girders joined by moment

building
◻ Consist of columns and girders joined by moment
resistant connections.
◻ Can build upto 20 to 25 floors
2)SHEAR WALL STRUCTURE
◻ Concrete or masonry continuous vertical walls may
serve both architecturally partitions and structurally to
carry gravity and lateral loading. Very high in plane
stiffness and strength make them ideally suited for
bracing tall building
◻ Usually built as the core of the building
◻ Can build upto 35 Floors
Shear wall core
21. 3)OUTRIGGER STRUCTURES
◻ The core may be centrally
located with
outriggers extending on both sides or in some
cases it may be located on one side of the
building with outriggers extending to the
building columns on the other side
◻ The outriggers are generally in the
form of trusses (1 or 2 story deep) in steel
◻
form of trusses (1 or 2 story deep) in steel
structures, or walls in concrete structures,
that effectively act as stiff headers inducing a
tension- compression couple in the outer
columns.
◻ Belt trusses are often provided to distribute
these tensile and compressive forces to a
large number of exterior frame columns.
◻ An build upto 150 floors

22. EXTERIOR STRUCTURES
1)Tube system
◻ The tube system concept is based on
the idea that a building can be
designed to resist lateral loads by
designing it as a hollow cantilever
perpendicular to the ground. In the
simplest incarnation of the tube, the
perimeter of the exterior consists of
closely spaced columns that are tied
closely spaced columns that are tied
together with deep spandrel beams
through moment connections. This
assembly of columns and beams
forms a rigid frame that amounts to
a dense and strong structural wall
along the exterior of the building.
◻ The different tubular systems are-
◻ 1)Framed tube 2)Braced tube
3)Bundled tube 4)Tube in
tube
23. 2)Diagrid systems
◻ With their structural efficiency as a varied
version of the tubular systems, diagrid structures
have been emerging as a new aesthetic trend for tall
buildings in this era of pluralistic styles.
◻ Early designs of tall buildings recognized the
effectiveness of diagonal bracing members in
◻
effectiveness of diagonal bracing members in
resisting lateral forces.
◻ Most of the structural systems deployed for early
tall buildings were steel frames with diagonal
bracings of various configurations such as X, K, and
chevron. However, while the structural importance of
diagonals was well recognized, the aesthetic
potential of them
was not appreciated since they were
considered obstructive for viewing the outdoors.
◻ Efficiently resists lateral shear by axial forces in the
diagonal members but have Complicated joints

York
24. 3)Space truss
◻ Space truss structures are modified braced
tubes with diagonals connecting the exterior to
interior. In a typical braced tube structure, all the
diagonals, which connect the chord members –
vertical corner columns in general, are located on
the plane parallel to the facades.
◻ However, in space trusses, some diagonals
penetrate the interior of the building.
◻
Bank of China, Hong Kon
◻ 4)Exo skeleton structure
◻ In exoskeleton structures, lateral load-resisting
systems are placed outside the building lines
away from their facades.
◻ Due to the system’s compositional characteristics,
it acts as a primary building identifier – one of the
major roles of building facades in general cases.
◻ Fire proofing of the system is not a serious
issue due to its location outside the building line.
Hotel de las Atres
25. 5)Super frame structures
◻ Superframe structures can create ultra
high-rise buildings upto 160 floors.
◻ Superframes or Megaframes assume
the form of a portal which is provided on
the exterior of a building.
◻ The frames resist all wind forces
◻ The frames resist all wind forces
as an exterior tubular structure. The
portal frame of the Superframe is
composed of vertical legs in each
corner of the building which are linked
by horizontal elements at about every
12 to 14 floors.
◻ Since the vertical elements are
concentrated in the corner areas of the
building, maximum efficiency is
obtained for resisting wind forces.
26. CONCLUSION
◻ With the present technology and known materials , it is possible to
build more higher and faster.
◻ It is now possible to build skyscrapers so fast using pre- fabricated
units that it can lead to environmental problems, stress on
resources and overcrowding if not controlled.
◻ To build higher the base of the building will have to be made
◻ To build higher the base of the building will have to be made
wider. The bundled tube system was a great innovation and was
able to span great heights during it's time , to attain the height of
burj khalifa the bundled tube system will need a bigger base when
compared with the buttressed core system.
◻ New improved structural systems and new materials in the
future can lead us to even greater heights and more stable
buildings. It’s not technology holding buildings back. It’s money.
