The document discusses ductility and ductile detailing in reinforced concrete structures. It states that structures should be designed to have lateral strength, deformability, and ductility to resist earthquakes with limited damage and no collapse. Ductility allows structures to develop their full strength through internal force redistribution. Detailing of reinforcement is important to avoid brittle failure and induce ductile behavior by allowing steel to yield in a controlled manner. Shear walls are also discussed as vertical reinforced concrete elements that help structures resist earthquake loads in a ductile manner.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
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.

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.

The application consumes very low space in disk. Therefore, the user can allocate very minimum local disk space for this application.
2. The basic approach of earthquake resistant design should be
based on lateral strength as well as deformability and
ductility capacity of structure with limited damage but no
collapse.
The code IS : 13920-1993 entitled “Ductile Detailing of
Reinforced Concrete Structures Subjected to Seismic Forces-
Code of Practice” is based on this approach.
This standard covers the requirements for anchorage,
specially bar cut-offs and joint details.
3. ▪ A ductile materials is one which can undergo large elongations
while resisting loads.
▪ When applied to reinforced concrete members and structures,
ductility means the ability to sustain significant inelastic
deformations before collapse.
▪ A brittle material fails suddenly while ductile material gives
sufficient warning before collapse thus saving many lives.
▪ It is very important to incorporate ductility into the structures
to make them earthquake resistant.
▪ To have sufficient ductility, the designer should pay attention to
detailing of reinforcement.
4. Ductility in the structure will arise from inelastic material
behavior and detailing of reinforcement in such a manner the
brittle failure is avoided and ductile behavior is induced by
allowing steel to yield in controlled manner.
If the structure is sufficiently ductile, it can resist unexpected
over loads, load reversals, impact, etc.
If the structure is ductile, the failure of the structure will not
be sudden. Hence the people occupying the structure get
sufficient time to escape.
5. It allows the structure as a whole, to develop its
maximum potential strength, through distribution of
internal forces, which is given by the combination
of maximum strengths of all components.
Building configuration must be simple and regular.
Individual members must be designed for ductility.
Connections and other structural details must be
carefully attended.
8. ▪
4. Overall ductility based on shear Vs
roof displacement
5. Storey ductility = story shear/ drift
9. ▪ Beams in RC buildings have two sets of steel reinforcement,
namely (a) longitudinal bars, placed along the length (b)
stirrups, placed vertically at regular intervals along its full
length.
▪ Longitudinal bars resist bending moment while vertical
stirrups resist shear force.
▪ Beams sustain two basic types of failures, namely:
1. Flexural failure
2. Shear failure
10. As the beam sags under the increased loading, it can fail in
two possible ways.
It relatively more steel is present on the tension face, concrete
crushes in compression, is a brittle failure and is therefore
undesirable.
If relatively less steel is present on the tension face, the steel
yield first and redistribution occurs in the beam until
eventually the concrete crushes in compression.
11. A beam may also fail due to shearing action.
A shear crack is inclined at 45° to the horizontal.
It develops at mid depth near the support and grows towards the
top and bottom faces.
Closed loop stirrups are provided to avoid such shearing action.
Shear failure is brittle, and therefore it must be avoided in the
design of RC beams.
12. The design and construction of RC buildings shall be governed by
the provisions of IS :456-2000.
For all buildings which are more than 3 storeys in height, the
minimum grade of concrete shall preferably be M20. But, for
buildings having more than 3 storeys in height and situated in
zones IV and V, the minimum grade of concrete should be M-25.
Steel reinforcement of grade Fe-415 or less only shall be used.
However, TMT bars of grades Fe-500 and Fe 550 having
elongation more than 14.5 % may also be used for the
reinforcement.
13. Clause 6.1 : General
The factored axial stress on the member under
earthquake loading shall not exceed 0.1 fck..
The member shall have width/depth ratio of more than
0.3
The width of the member shall not be less than 200 mm.
The depth of member (D) should not be more than ¼ of
clear span.
15. The positive steel at a joint face must be at
least equal to half the negative steel at that
face.
The steel provided at each of the top and
bottom face of the member at any section
along its length shall be at least equal to ¼ x
maximum negative moment steel provided
at the face of either joint.
In an external joint, both the top and the
bottom bars of the beam shall be provided
with anchorage length beyond the inner face
of the column, equal to the development
length in tension plus 10 times the diameter
of bar minus for 90 degree bend.
16. Clause 6.3 : Web reinforcement
Web reinforcement shall consist of vertical hoops. A
vertical hoop is a closed stimp having 135° hook with a 10
diameter extension (but not less than 75 mm) at each end.
In compelling circumstances, it may also be made up of
two pieces of reinforcement, a u-stimp and a cross tie.
The minimum diameter of the bar forming hoop shall be 6
mm. however in beams with clear span exceeding 5 m, the
minimum bar diameter shall be 8 mm.
17. ▪ The spacing of hoops over a length 2d at
either end of a beam shall not exceed
(a) d/4
(b) 8 x diameter of smallest longitudinal bar,
which ever is smaller.
▪ The first hoop shall be at a distance not
exceeding 50 mm from the joint face.
Else where, the beam shall have vertical
hoops at a spacing not exceeding d/2.
18. Clause 7.1 : General
These requirements apply to frame members which have a
factored axial stress in excess of 0.1 fck under the effect of
earthquake forces.
The minimum dimension of the member shall not be less than 200
mm.
The ratio of the shorter cross sectional dimension to the
perpendicular dimension shall preferably not be less than 0.4.
19. ▪ Clause 7.2 : Longitudinal reinforcement
▪ Lap splices shall be provided only in the central half
of the member length. It should be proportioned as a
tension splice.
▪ Any area of a column that extend move than 100 mm
beyond the confined core due to architectural
requirements.
20. Clause 7.3 : Transverse Reinforcement
Transverse reinforcement for circular column shall
consist of spiral or circular hoops.
In rectangular columns, rectangular hoops may be used.
The parallel legs of rectangular hoop shall be spaced not
more than 300 mm c/c. if the length of any side of the
hoop exceed 300 mm, a crosstie shall be provided.
The spacing of hoops shall not exceed half the least
lateral dimension of the column, except where special
confining reinforcement is provided.
21. ▪ Clause 7.4 : special confining reinforcement
▪ Special confining reinforcement shall be
provided over a length lo from each joint
face, towards mid-span and on either side of
any section, where flexural yielding may
occur under the effect of earthquake forces.
▪ The length lo shall not be less than,
1. Larger lateral dimension of the member
2. 1/6 x clear span
3. 450 mm, whichever is more.
22. When a column terminates into
a footing or mat, special
confining reinforcement shall
extend at least 300 mm into the
footing.
Columns supporting reactions
from discontinued stiff
members, such as walls, shall
be provided with special
confining reinforcement over
their full length.
23. Reinforced concrete (RC) buildings often have vertical plate like RC
walls called shear walls, in addition to slabs, beams and columns.
These walls generally start at the foundation level and are continuous
throughout the height of the building.
Their thickness can be as low as 150 mm or as high as 400 mm in
high rise buildings.
Shear walls are usually provided along both length and width of
buildings.
Shear walls like vertically oriented wide beams that carry earthquake
loads downwards to the foundation.
24.
25. Properly designed and detailed buildings with shear walls
have shown very good performance in past earthquakes.
The overwhelming success of buildings with shear walls
in resisting strong earthquakes is summarized in the
quote: “ we can not afford to build concrete building
meant to resist severe earthquakes without shear walls.”
27. ▪ The maximum spacing of reinforcement in either direction shall not
exceed the smaller of the followings.
1. Lw/5
2. 3. tw
3. 450 mm where lw = horizontal length of wall and tw = thickness of
wall web
▪ Nominal shear stress τv = vu/ tw. dw where vu = factored shear
force, dw = effective depth of wall = 0.8 lw (for rectangular section)
