This document discusses settlement of structures. It defines settlement as the vertical downward movement of a structure resulting from deformation of the supporting soil. Settlement includes three components: immediate/elastic settlement occurring within 7 days; primary consolidation settlement over time as pore water is expelled from saturated soils; and secondary compression of the soil skeleton. Differential settlement occurs when different parts of a structure settle by different amounts, potentially causing tilting. Common causes of settlement include excessive structural loads, weak soil compaction, changing groundwater levels, transpiration by plants, earthquakes, and drainage issues. Foundations must be designed to support dead loads, live loads, wind loads, and seismic loads without exceeding the soil's safe bearing capacity.

A foundation is a lower portion of building structure that transfers its gravity loads to the earth. Foundations are generally broken into two categories: shallow foundations and deep foundations. ... Once the foundation has been packed down tightly, or dried hard, we can begin to build the building superstructure.
Foundations provide support to the structure, transfers the loads from the structure to the soil. But the layer at which the foundation transfers the load shall have an adequate bearing capacity and suitable settlement characteristics. So it's important to know when and why Piling is done.

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.

3. SETTLEMENT
Settlement is the vertical downward
movement of structure
OR
The settlement of a structure is the result of
the deformation of the supporting soil,
OR
When a soil deposit is loaded, deformation
will occur due to change in stress. The total
vertical downward deformation at the
surface resulting from the load is called
Settlement.
5. SETTLEMENT
The total settlement of a foundation comprises three parts as follows
S = Se+Sc+Ss
where, S = total settlement
Se = elastic or immediate settlement
Sc = consolidation settlement
Ss = secondary settlement
Immediate settlement :
Immediate settlement takes place as the load is applied or within a time period of about 7 days.
Predominates in cohesion less soils and unsaturated clay
Immediate settlement analysis are used for all fine-grained soils including silts and clays with a degree of saturation <
90% and for all coarse grained soils with large co-efficient of permeability (say above 10.2 m/s)
Primary consolidation settlement :
The consolidation settlement is that part which is due to the expulsion of pore water from the voids and is time-dependent
settlement.
The leaning tower of Pisa in Italy has been undergoing consolidation settlement for over 700 years. The lean is caused by
consolidation settlement being greater on one side. This, however, is an extreme case. The principal settlements for most
projects occur in 3 to 10 years.
Dominates in saturated/nearly saturated fine grained soils where consolidation theory applies.
Here we are interested to estimate both consolidation settlement and how long a time it will take or most of the settlement to
occur.
Secondary settlement :
Secondary settlement normally starts with the completion of the consolidation. It means, during the stage of this settlement, the
pore water pressure is zero and the settlement is only due to the distortion of the soil skeleton
6. Settlement
Differential settlement
Footing resting on different type of soil, different bearing capacity and unequal load
distribution will result in the unequal settlement or what we call it a differential settlement .
Differential settlement can cause tilting of the structure. The Tower of Pisa in Italy is the
classic case study of the tilting of the tower at 5.5 degree southward and it is leaning from
1911 and is known as the “Leaning Tower of Pisa”. The reason for the leaning of the tower is
that in the southward side the clay soil is soft and hence more compressible than in the
northward side. There has been many strategies and attempt to prevent the tower from
collapse.
Uniform settlement :
Where foundation settlement occurs at roughly the same rate throughout all portions of
a building, it is termed uniform settlement.
9. SETTLEMENT
Bearing capacity :
if the structural load increased to the bearing capacity of soil
then there is the chances of settlement or foundation will
collapse, Each soil Bearing capacity is different from other.
Weak compaction:
When fill soils are not adequately compacted, they can
compress (settle) under the load of a foundation resulting in
damage to the structure
11. SETTLEMENT
GROUND WATER TABLE
It is important to note that both rising and falling groundwater levels can affect
soil behavior. Rise in GWT reduces the bearing capacity of the soil
Drag down and heave
When footing is located on a compressible soil, there is a chance of foundation
failure by drag down and heave. In plastic soils, new settlements (drag down)
are often accompanied by upward movements and heave some distance away
(Figure 2). When foundation failure does occur, it is usually the result of
differential settlement or heaving of the soil that supports the foundation.
12. SETTLEMENT
TRANSPIRATION => TREE/PLANTS :
We all know what perspiration is, but transpiration is a less commonly known
word. It is the word that describes plants removing moisture from the soil. Trees
withdrawing moisture from the soil in the summer can accelerate soil shrinkage
in hot summer months. It is the expansion and shrinking or contraction of soils
that disturb the foundation.
GROUND WATER TABLE
It is important to note that both rising and falling groundwater levels can affect
soil behavior. Rise in GWT reduces the bearing capacity of the soil
LATERAL LOADS :
Lateral movement in soil is possible when there is removal of existing side
support adjacent to a building or there is excessive overburden on backfill or
lateral thrust on the backside of a retaining wall. Lateral movement is also
observed during earthquake when structure fails due to lateral movement of soil
beneath the foundation
16. SETTLEMENT
Dead load : The dead load include the weight of materials
permanently fixed to the structure, such as beam, column, floors, walls
and fixed service equipment.
Live load : The live loads are the movable loads that are not
permanently attached to the structure. These loads are applied during a part
of its useful life. Loads due to people, goods, furniture, equipment etc. are
considered in live loads.
Earth quack
The force due to earthquake may be vertical, lateral or torsional on a
structure in any direction.
Earth pressure : Produce lateral force against the structure below the
ground surface or fill surface.
17. SETTLEMENT
Dead load and live load are computed by
tributary area method.
According to IS 1904-1978 foundation should
be proportioned for the combination dead load
+ live load and dead load + live load + wind
load or seismic load
The Foundation pressure should not the
exceed the safe bearing capacity by more than
25% for the combination of dead load, live
load and wind load
