The document discusses different types of staircases used in buildings. It describes straight stairs as the simplest form, consisting of steps leading in one direction across one or more flights. Quarter turn stairs make a 90 degree turn, saving space. Half turn stairs rise to a mid-level landing, turn 180 degrees, and continue parallel to the lower flight, allowing construction within a confined stairwell. The document provides technical details on staircase components like steps, risers, landings, and classifications to facilitate vertical movement between floors in an efficient and safe manner.

Basic Gyan On Staircase
Definition of staircase: a set of stairs and its surrounding walls leading from one level to another.
Functional Requirements: Circulation, Strength, Material, Safety, Ventilation all these aspects are important aspects of a functional staircase
Components: There are various architectural terms related to the staircase which should be learned at this stage to understand the topic better.
Headroom: The minimum clear height between the overhead soffit and the tread is called headroom.
Flight: The unbroken series of steps between the two landings is called the flight.
Landing: The leveled platform with no riser and tread on it placed between flights for resting during the use of stairs is called landing. The in-between landings are called mid landing.
Riser and Tread: Horizontal portion of step on which the foot is rested is called tread. The vertical portion of the step which gives height to the staircase is called riser.
Calculation Of riser and tread is an important and basic aspect for designing a staircase.
Standards for the staircase as per IS code helps in designing purpose with respect to users comfort and safety.
Nosing: The projection of the tread beyond riser increases the footrest area and aesthetics.
Scotia: Supports the projected area of the nosing to avoid breakages at the edges.
Waist Slab: Thickness of the slanted slab of the flight on which the steps are cast.
Line of Nosing: Imaginary line parallel to the nosing.
Stringers: Sloping members supporting the series of steps laterally are called stringers.
Pitch: Angle made by the line of nosing with the floor level is called the pitch.
Handrail: The rail fixed to the baluster to support the user while using the staircase is called handrail.
Balustrade: The series of vertical supports of the handrail running parallel to the steps is called Balustrade.
Newel Post: Vertical member placed at the starting and the end of the railing is called Newel post.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

2. INTRODUCTION TO STAIRS
Staircase is an important component of a building providing access to different
floors and roof of the building. It consists of a flight of steps (stairs) and one or
more intermediate landing slabs between the floor levels.
Stairs can be defined as series of steps suitably arranged for the purpose of
connecting different floors of a building.it may also be defined as an arrangement
of treads, risers, stringers, newel post, hand rails, and baluster, so designed and
constructed as to provide an easy and quick access to the different floors.
TIMBER STAIRCASE
3. STRENGTH-
Able to support for movement
between floors, including dead
and imposed load.
SAFETY –
The Building Regulation in
determining the rise ,tread,
headroom and dimensions of
the handrails and guarding.
Should be constructed of
materials that are capable of
maintaining strength and
stability for a period of time
sufficient to escape to the
outside.
FIRE SAFETY –
The steps and the width should
be adequate for the safe escape
to the outside.
FUNCTIONAL REQUIREMENTS-
TIMBER STAIRCASE
PRIMARY FUNCTIONS
Provide an access from one floor to
another.
Provide a safe means of travel between
floors.
Provide a degree of insulation where
part of a separating element between
compartments in a building.
Provide an easy mean of travel between
floors.
Provide a suitable means of escape in
case of fire.
Provide a mean of conveying fittings and
furniture between floor levels.
Note: For residential buildings the size of
step commonly adopted is 250 mm x 160
mm. For public buildings the adopted size
of step varies from 270 mm x 150 mm to
300 mm x130 mm.

TECHNICAL TERMS
TIMBER STAIRCASE
Step - It is a portion of stair which permits
ascent and descent. It is comprised of
a tread and riser.
Tread - It is the upper horizontal portion of a
step upon which the foot is placed
while ascending or descending.
Riser - The vertical portion of a step
providing support to the tread.
Flight - A series of steps without any platform,
break or landing in their direction.
Uninterrupted series of steps between
floor and landing, or between landing
and landing.
•A flight should have no fewer than
3 steps and no more than 16 risers.
•The rise and tread in one flight and
landings between floors should be
equal.
•The rise and tread should have the
same size to avoid interruption in the
rhythm of going up or down.
•The dimension of the riser and
thread will determine whether the
stair is steep or shallow.
TECHNICAL TERMS
6. TECHNICAL TERMS
Going of Step - It is the horizontal distance
between two successive riser faces.
Rise of steps - It is the vertical distance
between two successive tread faces
Landing- A platform or resting place provided
between two flights. A landing extending
right across a stair case is termed as half
space landing and the one extending only
half across a staircase is called a quarter
space landing.
Nosing- It is the projecting part of the tread
beyond the face of the riser. It is
rounded to give good architectural effect.
Scotia- It is a molding provided under the nosing
to improve the elevation of the step.
Line of Nosing-It is an imaginary line touching of each
tread and is parallel to the slope of the
stair
Head room- A clearance height between the pitch line
of the stair and the underside of the stairs,
landings and floors above the stair minimum
2 m clearance from the pitch line

7. Baluster: It is vertical member of wood or metal
supporting the hand rail.
Balustrade: Consists of row of balusters surmounted
by a rail.
Hand Rail: Horizontal member fixed on the top of
series of balusters. Can be made from
timber or steel.
Newel post: This is the vertical member which is
placed at the ends of flights to connect
hand rail.
Soffit: It is the underside of a stair.
Waist: The thickness of structural slab in case of
an R.C.C. stair is known as a waist.
Pitch or slope: It is the angle which the line of nosing of
the stair makes with the horizontal.
Winders: These are tapering steps which are
provided for changing the direction of a
stair.
Strings or stringers: These are the sloping wooden
members which support the steps in a
stair. They run along the slope of the
stair.

9. STRAIGHT STAIRS
TIMBER STAIRCASE
STRAIGHT STAIRS
• All steps lead in one direction.
• Simplest form of stair arrangement.
• It may consist of one or more flights.
• They are used when space available for staircase is long but narrow
in width.
• If the ascending is steep, the straight flight may be broken at an
intermediate landing.
10. QUARTER TURN STAIRS
TIMBER STAIRCASE
QUARTER TURN STAIRS(L-SHAPED)
• A stair turning through one right angle is known as Quarter turn
stairs. (L-shaped stair)
• Good in compact planning.
• The quarter turn sometime will be replaced with winders for
economic use of space.
11. HALF TURN STAIRS (DOG-LEGGED,OPEN-NEWEL)
• Rises to a landing between floors, turns through 180˚, then rises
parallel to the lower flight to the floor above.
• The most common arrangement of stairs.
• Advantage – can be constructed within the confined vertical stair
well.
• In case of open newel stair, there is a well or hole or opening
between flights in plan.
• This well may be rectangular or of any geometrical shape and it can
be used for fixing lift.
• These staircase are useful where available space for staircase has a
width greater than twice the width of steps.
