BUILDING FRAME
Kerangka Bangunan
Building Frame and Construction
• In construction, the building frame is known as
light-frame construction. It is a building technique
based around vertical structural members. The
vertical structure will provide base for the internal
and external construction of the building.
• Di dalam sesuatu pembinaan, rangka bangunan juga
dikenali sebagai pembinaan rangka-ringan. Ia
merupakan satu teknik yang merangkumi beberapa
struktur menegak. Struktur menegak atau rangka ini
menyediakan satu asas bagi pembinaan luar dan
dalam bangunan.

What is building frame
Framed buildings are building structures
formed by the framed elements usually in the
form of columns and beams, as well as
further strengthened as necessary by the
introduction of rigid floor membranes and
external walls
A - Column
B - Ground beam
C - Foundation
D - Beam
E - Fascia
F - Strut
G - Rafter
H - Ceiling joist
I - Ridge
J - Tie
Types of Building Frame
Timber Frame
• Timber frame is one of the oldest forms of
construction, going back to the days when homes
and other buildings were built out of logs
• Timber framing construction are traditional
methods of building with heavy timbers, creating
structures using squared-off and carefully fitted
and joined timbers with joints secured by large
wooden pegs
• Load bearing timber wall for small building may
be constructed by creating a framework.
Timber frame
Steel Frame
Steel frame also known as "skeleton frame" of
vertical steel columns and horizontal I-beams,
constructed in a rectangular grid or any other grid
to support the floors, roof and walls of a building.
The development of this technique made the
construction of the skyscraper possible.
Rangka keluli merupakan struktur menegak dan melintang
yang dibina dalam bentuk segi empat atau pelbagai jenis
bentuk bagi menampung beban lantai, bumbung dan
dinding sesebuah bangunan. Pengenalan teknik binaan ini
menjadikan pembinaan bangunan pencakar langit lebih
mudah.
Steel Frame
Reinforced Concrete Frame
• The reinforcement concrete frame is
the vertical and horizontal frame that is
made by using concrete. It is usually
accompanied with steel reinforcing
bars.
• Rangka ini merupakan rangka menegak dan
mendatar yang dibuat menggunakan konkrit sebagai
bahan utama dan asas. Keluli pengukuh akan
dimasukkan dalam konkrit bagi mengukuhkan lagi
binaan.

Pre Fabricated/
Pre Cast Concrete Frame
• Prefabricated frame is a type of building that
consists of several factory-built components or
units that are assembled on-site to complete the
unit

WALL
Dinding
WALL
Definition
A wall is defined as a continuous, vertical, solid
structure of brick, stone, concrete, timber or metal,
thin in proportion to its length and height which
encloses and protects a building or serves to divide
buildings into compartments or rooms.
Dinding merupakan sambungan berterusan, menegak dan
struktur kukuh yang diperbuat samada daripada batu,
konkrit, kayu atau pun besi, tidak terlalu tebal bagi lebar
dan panjangnya yang akan bertindak sebagai pelindung
dan membahagi bangunan kepada beberapa bahagian.

Materials
Some of the most popular materials that are used for
walls are:
Stone Concrete
Brick Steel
Timber Glass
Types of Wall
Solid Wall
Frame Wall
Constructed either Load bearing Carries
brick, blocks of wall imposed
loads & dead
stone, or concrete
laid in mortar load
Constructed Non
from a frame loadbearing
of small wall
sections of
timber,
reinforced
concrete or
metal.
What is the difference
between a load bearing and a non
load bearing wall ?
A load bearing A non load
wall is bearing wall only
a wall that bears supports its own
structural weight weight
along with its
own
Functional Requirements Of A Wall
Strength
Stability
Resistance to weather & ground moisture
Durability & freedom from maintenance
Fire safety
Resistance to the passage of heat
Resistance to the passage of sound
Functional Requirements
1. Strength
• A good wall can bear the wind load, dead &
imposed load from floor & roof
• The strength of the wall also depends by the
material used, wall thickness & the way material
are put together
2. Stability
• The stability of wall may be affected by
foundation movement, lateral forces -wind &
expansion due to temperature & moisture
change
Functional Requirements
3. Resistance to weather & ground moisture
• Building regulation- wall must adequately
resist the passage of moisture to the inside of
the building.
• Moisture may penetrate into a wall by
absorption of water from the ground that is
in contact with foundation walls or through
rain falling on the wall
How To Prevent Passage Of The Moisture Or
Water?
Damp Proof Course (DPC)
- Act as a barrier to the passage of the moisture or
water between the parts separate by the dpc.
- There should be a continuous horizontal dpc above
ground in walls whose foundations are contact with
the ground – to prevent moisture from the ground
rising through
- The dpc should be continuous for the whole length
and thickness of the wall and at least be at 150mm
above finished ground level to avoid the possibility
of a build up of material against the wall and acting
as bridge for moisture from the ground.
The movement of moisture or water maybe
upwards in the foundation walls and ground floors.
Functional Requirements
4. Fire safety
• Building regulation set standards to provide
means of escape, limitation of fire spread,
provide access & facilities for the fire service
Windows & doors may used as a means of
escape
Fire safety
Functional Requirements
5. Resistance to the passage of sound
• Sound is transmitted as airborne sound &
impact sound
Airborne sound i.e. a radio. The vibration in the
air caused by the sound source
Impact sound is caused by contact with a
surface, i.e. slamming of a door or footsteps on a
floor which set up vibration in walls and floor
The building regulations require walls to
provide reasonable resistance to airborne sound
between building spaces
Resistance to the passage of sound
Elements Of An Opening
Elements Of An Opening In A Wall
Elements Of An Opening
1. Head/Lintel
• Function- head is to carry the load of brickwork and
transmit this load to jambs.
• A variety of materials and methods is available
1. Timber (light loads & small span)
2. Steel (painted with bituminous to give the protection
against corrosion)
3. Concrete (design as in situ or precast reinforced
lintel & used for all spans)
4. Stone
5. Brick (suitable for small spans up to 1m)
Elements of opening
2. Jambs
• The brickwork acts like legs which support
brickwork over the head
• Two types of Jambs :
1. plain or square jambs
2. rebated jambs
Elements of opening
3. Reveal
• Describe the thickness of the wall
4. Sill
• The lower part of the opening
• Function of a sill
― to protect the wall below a window
• Appearance and durability are the main
requirement
• Sill is not a member which is needed to carry
heavy load
