Stairs are designed to provide passage between different levels of a building. They consist of steps divided into smaller vertical distances. Stairs should be located for easy access and be well-lit and ventilated. There are various technical terms used in stair construction like baluster, handrail, newel post, soffit, and tread. Stairs can be straight, turning, circular, or geometrical. Straight stairs run in one direction while turning stairs change direction. Circular stairs have winder steps radiating from the center. Geometrical stairs have non-rectangular shapes with continuous handrails. Proper stair design and construction is important for safety and accessibility.

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.

Stairs are used to create a pedestrian route between different vertical levels by dividing the height between the levels into manageable steps. Very generally, the word 'stairs' refers to a staircase, whereas the word 'step' refers to the steps that make up the staircase.
The type of stairs suitable for different situations will depend on:
The supporting structure.
The amount and type of usage it is likely to receive.
The space available and its geometry.
The difference in height between the top and bottom.
Materials selection
Stairs may be:
Open tread or closed tread.
Provided with handrails on one or both sides, or in the middle on wide stairs.
Enclosed by walls or open on one or both side.
Different widths and lengths and may have a range of step dimensions.
Different geometries.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Ch3 stair cont..
1. What is stairs ?
“A Stair is a system of steps
by which people and
objects may pass from one
level of a building to
another.”
A stair is to be designed to
span large vertical distance
by dividing it into smaller
vertical distances, called
steps.
2. Location of Stairs
It should be so located as to provide easy access to the
occupants of the building.
It should be so located that it is well lighted and
ventilated directly from the exterior.
It should be so located as to have approaches
convenient and spacious.
It public building it should be located near main
entrance and in residential building it should be
placed centrally.
4. The definitions of technical terms used in connection with
the stairs are as follows:
1) Baluster :-
It is vertical member of wood
or metal supporting the hand rail.
2) Handrail :-
The inclined rail over the
string is known as a handrail.
3) Newel post :-
This is the vertical member which is placed at
the ends of flights to connect hand rail.
4) Soffit :-
It is the underside of a stair.
5) Waist :-
The thickness of structural slab in case of an
R.C.C. stair is known as a waist.
5. 6) Nosing :-
It is the projecting part of the tread
beyond the face of the riser.
It is rounded to give good architectural
effect.
7) Scotia :-
It is a moulding provided under the nosing
to improve the elevation of the step.
6. 8) Step :-
It is a portion of stair which permits ascent and
descent.
It is comprised of a tread and riser.
9) Tread :-
It is the upper horizontal portion of a step upon
which the feet is placed while
ascending or descending.
10) Rise :-
It is the vertical distance
between two successive tread faces.
11) Going :-
It is the horizontal distance
between two successive riser faces.
7. 12) Flight :-
A series of steps without any platform, break or
landing in their direction.
13) Landing :-
It is the level platform at the top or bottom of a
flight between the floors.
14) Run :-
It is the total length
of stairs in a horizontal
plane, including landings.
8. 19) Winders :-
These are tapering steps which are provided for
changing the direction of a stair.
20) Strings or stringers :-
These are the sloping wooden members
which support the steps in a stair. They run along the slope of
the stair.
There are two types of string :
i) a cut or open string
ii) a closed or housed string
In the cut or open string , the upper edge is cut away to
receive the ends of steps.
In the closed or housed string, the ends of steps are
housed between straight parallel edges of the string.
9. 21) Balustrade or Barrister :-
The combined framework of
handrail and balusters is known as the balustrade or
barrister.
22) Walking line :-
The approximate line of movement of
people on a stair during ascending or descending is
known as a walking line and it is situated at a distance
of about 450 mm from the centre of handrail.
10. Types Of Steps..
Steps in a stair may be of following types :
1) Bull nose step
2) Round ended step
3) Filer
4) Splayed step Commode step
5) Dancing step or Balancing step
6) Splayed step
7) Winder
11. 1) Bullnose step :-
It is generally provided at the bottom of the flight , projecting in
front of the newel post. Its end near the newel forms the quadrant of a circle.
2) Round ended step :-
A round ended step is similar to a bullnose step except that
it has a semi–circular end which projects out from the stringer.
3) Filer :-
A filer is an ordinary step of uniform width and rectangular shape in
plan.
Round ended step
12. 4) Commode step :-
A commode step has curved tread and riser.
5) Dancing steps or Balancing step:-
Dancing steps are the
winders which do not radiate from a common centre.
13. 6) Splayed step :-
This step has one end or both ends splayed
in plan.
7) Winders :-
Winders are tapering steps, such as those which
radiate from a point usually situated at the centre of a
newel post.
15. 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.
Plan
Elevation
16. •The width and the length of the landings should be
equal.
Straight-stairs-with-intermediate-landing
18. In case of turning stairs ,flights take turn. The types of
turning stairs are:
1. Quarter turn stairs:
A stair turning through one right angle is known as
Quarter turn stairs. (L-shaped stair)
• If a quarter turn stair is branched into two flights at a landing is
known as a Bifurcated stair.
• This types of stair is commonly used in the public buildings
near the entrance hall .
• The stair has a wider flight at bottom which bifurcates into two
narrower flights at the landing.
19. -one turn into left and the other to the right.
•This staircase has either equal or unequal flights.
20. 2. Half Turn Stairs:
•A stair turning through right angle is known as Half Turn Stairs.
•A half turn star may be of dog-legged type or open newel type .
Dog-legged stair Open newel stair
DOG-LEGGED STAIR
•Two short flights with a half space landing between them.
• In case of dog-legged stair, the flights run in opposite directions
and there is no space between them in plan.
21. • Its name is derived from its appearance in the sectional
elevation.
•This stairs are useful where total width of space available for the
staircase is equal to twice the width of steps.
OPEN NEWEL STAIR
•Space between the upper and lower flights causes half space
landing to be longer.
•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.
22. 3. Three quarter turn Stair
•A stair turning through three right angles is known as a three
quarter stair.
•In this case ,an open well is formed. This types of stair is used
when the length of the staircase is limited and when the vertical
distance between the two floor is quite large.
23.
24. the steps radiate from the center and they do not have
either any landing or any intermediate newel post…..
Some of the important facts to be noted in connection
with the circular stairs are:
1. flights consist of winders only and may be continued
through any number of turns.
2. may be constructed of a cast iron or mild steel or
concrete. Usually its structural design and construction
of are complicated in nature.
25.
26. 3. For concrete spiral stairs, the steel reinforcement is
heavy and formwork is complicated. These make the
concrete spiral stairs expensive.
4. The core of spiral stair may be solid or hollow and the
stair may be provided with cut or closed strings.
5. The spiral stairs are useful where the space available is
limited and where the traffic is less. Eg., shops
28. which has rounded corners or is
circular or elliptical and that have
the strings and rails arranged upon
geometric principles and running
continuously from top to bottom.”
29. have any geometrical shape and requires no newel
posts.
The handrail continues without interruption and
without any angular turns.
Its construction requires considerable skill and it is
weaker than corresponding open newel stair.
30. (4) The treads and risers are supported on the angles
which are connected to the stringers.
(5) The risers may be totally omitted in some cases.
(6) The spiral stairs of cast-iron consist of a cast-iron
newel fixed in the centre around which the cast-iron
steps are fixed.
(7) For metal stairs the metal balusters with handrail of
pipe are used.
