This document discusses parapet walls. It defines a parapet wall as a short wall built on the edge of a roof, balcony or terrace that is usually between 3-4 feet high. Parapet walls provide both safety and aesthetic benefits. They prevent things from falling off the edge and help improve the appearance of a structure. The document outlines purposes of parapet walls such as protection, preventing dust/debris from entering, and hiding equipment. It also discusses design considerations like minimum height, durability, serviceability and aesthetic choices.

3. WHAT IS A PARAPET
WALL
• If a short-height (3ft-4ft) wall is built on the
edge of the roof, balcony and terrace of
the house, it is known as a parapet wall. It is
also built on bridges and sidewalks.
• Various materials such as brick masonry,
steel, RCC (reinforced cement concrete),
aluminum, glass are used for parapet wall
construction. It gives our home an
attractive look.
• It helps to improve the appearance of the
house and also acts as a safety barrier for
the occupants.
• A parapet wall is a low-security structural
layer built near the roof. this wall provides
continuity and support in terms of water,
air, steam and thermal control.
• Control of these factors can help prevent
degradation and corrosion of the roof or
some other pre-built adjacent structure.

4. PURPOSES OF
PARAPET WALL
The terrace of the house is used by the
occupants for sitting, relaxing, browsing
and many other recreational activities.
Therefore, the safety of the residents
provided with the parapet should be
ensured. A parapet wall serves the
following purposes.
a) Giving an aesthetic look to the
structure.
b) Provide protection to prevent
vehicles from falling off the bridge on
bridges, even when humans are on the
rooftop.
c) Prevent dust from entering the air
through the roof.
d) To prevent concealment of
equipment and machinery on the roof.
e) To prevent debris collected on the
roof from falling.
f) Perforated walls will be useful for
security operations in military areas.
g) To prevent excessive wind loads from
coming on the roof

5. SAFETY
• A property is an attribute of a
program that is true for every
possible execution of that program.
• Properties of interest for concurrent
programs fall into two categories:
safety and liveness.
• A safety property asserts that
nothing bad happens during
execution.
• A liveness property asserts that
something good eventually
happens.
• Another way of putting this is that
safety is concerned with a program
not reaching a bad state and that
liveness is concerned with a
program eventually reaching a
good state.
• The standard minimum height of the
parapet wall should be 3feet-
900mm.The parapet wall should not
be built less than 3 feet.

6. DURABILITY
• The wall should be durability by
doing painting and masonry
works properly.
• The finishing works of wall should
be fine enough. So that, it will be
long lasting upto a long time.

7. SERVICEABILITY
• Serviceability of wall should be
maintain once in a year. So that,
the wall should not be damage
or cracked.

8. • It should be built of their own
choice.
• The parapet can be built as far
their different and shape; like
circular, square, rectangular, etc.
