Wall Flashcards
The structure has beams and slabs but not columns.
Load bearing walls
In simple words, whether its exterior or interior walls, the wall which is bearing the whole weight of the structure,
including self-weight of structural elements.
Load bearing walls
Strip foundation is adopted for the load-bearing type of wall. Ff:
- PRECAST CONCRETE WALL
- CAST IN PLACE CONCRETE WALL
- MASONRY WALL
- PRE PANELIZED LOAD BEARING METAL STUD WALLS
- RETAINING WALL
It is a ready-made wall where the wall is
cast in the factory and bought to site to
install it
Precast concrete wall
You need to specify the length and
height of the ________. The _______ is cast and
transported to the site.
Wall
This type of wall is preferred where there
is limited to space to work and where
there is less chance of labor
Precast concrete wall
The primary purposes of the
________ are to transfer load to the
supporting structure and provide stability
Connection
The ________ for precast concrete panels are an important component of the envelope system.
Connections
The criteria used to design precast
connections including but not limited to
:
• Strength
• Ductility
• Volume change accommodations
• Durability
• Fire resistance
• Constructability
The ________ between precast units or between precast and
other building components must be maintained to prevent
leakage through the precast wall system.
Joints
It should consider the structural, thermal, and all other factors that affect the performance and movement of
a joint.
Joint design
It should of course be adequately
designed to withstand the movement of the joint.
Joint seal
ints between panels must be wide enough to accommodate _________ and __________ between panels.
thermal expansion and differential
movements
INSTALLATION OF PRECAST
CONCRETE WALL
- Inspection of site
- Setting out
- Mobilization
- Preparation on site
- Locate closest grid lines and guide level
- Installation shall be done by Tower or Mobile Cranes available on site
- Make sure that temporary supports are adequate
- Grouting works, bolted or welded joints and connections must comply with applicable
requirements indicated in the plan. - Field cutting of precast, prestressed concrete members is not permitted without approval of the Engineer.
- Do not use drilled or power-actuated fasteners for attaching accessory items to precast, prestressed concrete members unless approved by the engineer.
ADVANTAGES of construction of a precast villa superstructure :
• Saves Construction Time
• Usage of Pre-stressed Concrete
• Quality Assurance
• Aesthetics
• Durability
• Cost-effective
• Safe Construction Sites
DISADVANTAGES of construction of a precast villa superstructure:
• High Initial Investment
• Transportation Issue
• Handling Difficulties
• Modification
• Sensitive Connection Works
Are made with ready -mix concrete placed into removable forms erected on site
CAST-IN-PLACE (CIP) CONCRETE WALLS
Casting concrete in place involves
a few distinct steps :
placing formwork
placing reinforcement
and pouring concrete
They usually place forms at the corners first and then fill in between the corners
Builders
It can beerected before either form face as a cage or after one side of the formwork is installed.
Rebar
It should always be filled at an
appropriate rate based on formwork manufacturer recommendations to prevent problems
Forms
It is used for building exterior wall cladding. The metal can be stainless steel, copper,aluminum. It supports gravity, seismic and wind loading
PRE PANELIZED LOAD BEARING METAL STUD WALLS
Are pre-fabricated off-site in a plant utilizing welded connections and very tight tolerances to achieve the highest qualityavailable
PRE PANELIZED LOAD BEARING METAL STUD WALLS
A strong structure that is made to keep a hill, slope or mound of earth in
place. Unlike indoor walls, retaining
walls receive pressure horizontally
instead of vertically
Retaining wall
Types of retaining walls:
Gravity Retaining Wall
Cantilevered Retaining Wall
Sheet Piling Retaining Wall
Anchored Retaining Wall
The wall is built of individual
blocks of materials such as brick,
clay or concrete blocks, or stone,
usually in horizontal courses
bonded together with some form
of mortar
Masonry walls
Types or includes in masonry walls:
Brick wall
Concrete blocks
Stones
Because of this, the material is frequently used in passive
solar designs that capture and use solar
radiation to help heat
a building
Masonry’s high thermal mass
Advantages of masonry walls:
• The final load bearing masonry
structure constructed is highly
durable and solid.
• This structure type possesses high
fire resistance.
• Advance preparations or fabrication
is not required for this type of
construction.
• Load bearing masonry structures are
aesthetically attractive.
• The tools and equipment used for
masonry construction are simple
and cheap.
Disadvantages of masonry walls:
• Load bearing masonry structure
performs badly during the action of
earthquakes.
• Load bearing masonry construction
employs more labor.
• Load bearing masonry construction
is slow.
• The weight of the load bearing
masonry structure is high.
• The thermal insulation properties of
these structures are very poor.
Proper storing of masonry materials
Concrete masonry units should be stored and laid in a dry condition.
Adequate bonding must be provided where masonry walls intersect
Concrete masonry units must be dried to the specified moisture content before use. After drying, they should be stored off the ground and protected from rain.
During hot weather, the workability of mortar and the length of time that it remains workable may be considerably reduced.
They only carry their own weight and does not support any structural members such as beams and
slabs.
Non load bearing walls
These walls are just used as partition walls or to separate rooms from outside.
Non load bearing walls
Non load bearing walls is also known as
Interior wall
Types of material used in a non load bearing walls
Hollow concrete block
Facade bricks
Hollow bricks
