Concept:

CBR test is strength test conducted on the soil by introducing surcharge load at the compaction rate of 1.25 mm per minute on a completely soaked soil sample passing through 20 mm sieve size.

δ = displacement in mm

Pδ = Load corresponding to ‘δ’ settlement

Ps = Load for standard crushed aggregate:

At 5 mm penetration Standard load Ps = 2055 kg

At 2.5 mm penetration standard load Ps = 1370 kg

Calculation:

Given,

Sustained load at 5 mm penetration = 120 kg

At 5 mm penetration,

By Clause 17.13.5.3 of IS 800-2007

A weir which the water level on the downstream side of a weir is above the crest of the weir is called Submerged weir or Drowned weir.

The Cippoletti weir is a trapezoidal weir, having side slopes 1 horizontal to 4 vertical. The purpose of the slope, on the sides, is to obtain an increased discharge through the triangular portions of the weir, which otherwise would have been decreased due to end contractions in the case of rectangular weirs.

A type of contracted weir that is related to the rectangular sharp-crested weir is Cippoletti weir, which has a trapezoidal cross-section with side slopes 1: 4 (H: V).

Three-phase diagram:

A soil as a three-phase system consisting of solid particles or soil grains), water and air. The void space between the soil grains is filled partly with water and partly with air. The diagram which represents all the three components of soil i.e., solids, air, and water is called a three-phase diagram.

Weight of air is assumed Zero

Concept:

Minimum pitch of bolt connection = 2.5 d

Where, d = diameter of the bolt

Calculation:

Given;

d = 20 mm

Minimum spacing = 2.5 × 20 = 50 mm

Pozzolanic materials are essentially siliceous or aluminous compounds which in themselves do not possess any Cementous property but when finally divided in the presence of water reacts with calcium hydroxide formed during hydration of cement resulting in the formation of the compound that possess cementing property.

• It increases the workability
• It can reduce permeability
• Reduces water evaporation
• Honey combing will be reduced
• Improves cohesion that means less segregation
• Increases the elastic modulus of concrete
• Less heat of hydration
• It increases the resistance of concrete to attack by salts and sulphates.
• It can reduce shrinkage, creep, and bleeding
• Leaching in concrete reduces
• Used in mass concreting
• It is particularly used in marine and hydraulic structure

Disadvantages:

• Curing period is more for PPC
• Earliest strength gain is less

Dummy activity:

• While establishing the relationships and drawing the network diagram sometimes it so happens that there does not exist any real activity between two events but an event cannot be said to have occurred unless and until some other event has occurred.
• Such cases are shown on the network diagram as dummy activities.
• The purpose of dummy activity is to maintain the logic of a network diagram.
• Since no real activity takes place between two such events, the dummy activity does not consume any resources.
• It also does not consume time duration.
• Dummy activities are used only in case of absolute necessity.
• Dummy activities consume no time or resources.

By convention, dummy activities are represented by a dashed arrow on the project network.

In the following diagram both activities A & B have the same beginning and end events.

The above network diagram is incorrect because it breaks the rule of assigning unique numbers to each activity for the purpose of identification. The following network diagram demonstrates the principle of using a dummy activity for overcoming the problem of parallel activities with identical start and finish.

Therefore, a dummy activity is created to make activities with common starting and finishing events distinguishable and also to identify and maintain the proper precedence relationship between activities.

Critical Path:

• The longest path in the network diagram is called the Critical Path.
• The length of the Critical Path determines the minimum duration required for the completion of the project.

Critical activity:

• Critical activities are those activities that lie on the critical path.
• The float of activities that lie on the critical path is zero.

Float:

• Relax or delay provided to any activity is known as float.

Slack:

• Slack is the amount of time a task can slip before it bumps into another task.

Slack is of two types:
Slack of head: It is the difference between the latest finish time and the earliest finish time (Lj - Ej) at the completion of an activity (end of the arrow).

Slack of tail: It is the difference between the earliest start time and the latest start time (Ej - Lj) at the start of an activity (start of an arrow).

Floats are of three types. They are as follows:

Total Float (TF):
The maximum delay or relax provided to any activity without affecting the project duration.
TF = Lj – Ei – dij

Free Float (FF):
Relax or delay provided to any activity without affecting the Earliest Start Time (EST) of the successor activity.
FF = Ej – Ei – dij

Independent Float:
Relax or delay provided to any activity without affecting the Earliest Start Time (EST) of successor activity as well as Latest Finish Time (LFT) of the predecessor activity.
IF = Ej – Li - dij
Relation among float TF ≥ FF ≥ IF
On the Critical path, total, free, and independent float are all equal and zero.

Concept:

Vortex flow:

The motion of a fluid in a curved path is known as vortex flow.

When a cylindrical vessel containing some liquid is rotated about its vertical axis, the vortex flow will be followed by liquid.

Vortex motion is of two types:

1. Forced vortex:

• In the forced vortex, fluid moves on the curve under the influence of external torque.
• Due to the external torque, a forced vortex is a rotational flow.
• As there is the continuous expenditure of energy, Bernoulli's equation is not valid for forced vortex.
• For forced vortex, v = rω is applicable.
• Examples:
  • The flow of water through a runner of the turbine.
  • Rotation of water in the washing machine.

2. Free vortex:

• When no external torque is required to rotate the fluid mass, that type of flow is called a free vortex.
• As there is no torque in the free vortex, so free vortex is an irrotational flow.
• For free vortex, a moment of momentum is constant i.e. vr = constant.
• Examples:
  • The flow of liquid through a hole provided at the bottom of a container.
  • Draining the bathtub.

∴ Vortex flow is both rotational and irrotational flow depending on the torque applied.

Concept

For 30° bends length of crack =

Length covered by crank =

∴ Extra length required for one bend = 2.00 d - 1.73 d = 0.27 d
Thus, if a bar cranked at both ends at 30° then the total length of the bar = L + 2 × 0.27 d = L + 0.54 d

∴ Increase in length = 0.54 d = 2× 0.27 d

Concept:

In a dual wheel assembly, let d is the clear gap (or distance) between the wheels.
s is the spacing between the centres of the wheel.
ESWL is given by

Where,

ESWL = Equivalent single-wheel load
z = desired depth
P = Wheel load

Calculation:

Given
At complete stress overlap, ESWL = 2P

z = 2s

If the load dispersion is assumed to be at an angle 45^∘ the complete stress overlap happens at a depth of 2s measured from the surface of contact.

Note:- Upto depth d/2 (or z = d/2), no stress overlap occurs.

Hence option (3) is correct.

Let us assume the concentrated load = P(or W)

RA + RB = P ---(1)

∑MB = 0

R_A = P/2
R_B = P/2

The BM will be maximum on the point at which shear force changes its sign.

So the value of bending moment at a distance x = L/2 is:

Methods to determine unit weight:

1. Core cutter method:
It is a field test used to determine unit weight of soil. It is used only when the core cutter is easily driven i.e for soft cohesive soil and when the surface of soil is exposed.

W1 = Weight of empty core cutter
W2 = Weight of cone cutter with soil
Wsoil = W2 – W1
γt = Wsoil / Vsoil
∴
Where, γt = Bulk unit weight and ω = water content of soil sample

2. Sand Replacement method:
It is a field method used for stony or gravelly soilin which core cutter cannot be easily driven.

3. Water displacement method:
It is a lab method used when chunk of soil is taken from field to lab.

Roof Trusses:

• Roof trusses are often used as industrial building frames, The roof load is transmitted to the truss at the joints by means of a series of purlins. The roof truss along with its supporting columns is termed as bent.
• To keep the truss rigid, and thereby capable of resisting horizontal wind forces, knee braces are sometimes used at the supporting columns.
• The space between the adjacent truss is called a bay.
• Bays are often tied together using diagonal bracing in order to maintain the rigidity of the building's structure.
• Trusses used to support roofs are selected on the basis of the span, the slope, and the roof material. Some of the more common types of trusses used are shown in the figure below.
• The scissors truss can be used for short spans that require overhead clearance.
• The Howe and Pratt trusses are used for roofs of moderate spans of about 18 m to 30 m. For larger spans, the fan truss or Fink truss may be used
• If a flat roof or nearly flat roof is to be selected the Warren truss is used.
• Sawtooth trusses are used where column spacing is not objectionable and uniform lighting is important.
• The bowstring truss is sometimes used for garages and small airplane hangars.
• The arched truss is used for high rises and long spans such as field houses, gymnasiums, and so on.

Hence the given figure in question is the French or Cambered Fink-type truss.

Concept:

Coagulation:

• It is the process in which certain chemical terms as coagulants are added in the wastewater so as the neutralize negative protective charge over the particle to increase their opportunity to come in contact with each other, thus grow in size and get easily settled in following sedimentation process.
• To neutralize the charge over the suspended impurities minimum energy (threshold energy) is required which is provided by induced fast mixing in this process.
• To remove the inorganic forms of phosphate by the addition of a coagulant and a mixing of wastewater and coagulant.

Flocculation:

• Flocculation is the process in which neutralize particle is brought in intimate contact with each other to promote their agglomeration resulting in increased size of flocs, which can get easily settled in the following sedimentation process.
• To increase the opportunity of the neutralized particle to come in contact with each other slow mixing is induced during flocculation.

Eutrophication:

• It is an enrichment of water by nutrient salts that causes structural changes to the ecosystem such as increased production of algae and aquatic plants, depletion of fish species, general deterioration of water quality, and other effects that reduce and preclude use.
• It is caused by human activities because they are responsible for the addition of 80% nitrogen and 75% phosphorous in lakes and streams.
• Some phosphorus-rich sources that enrich water bodies with the nutrient include Fertilizers, Untreated sewage, Detergents containing phosphorus, and Industrial discharge of waste.
• ​Among these sources, the primary contributors to eutrophication include agriculture and industrial wastes.

Concept:

Unit Hydrograph:

It is defined as the direct runoff hydrograph resulting from one-unit depth (1 cm) of excess rainfall occurring uniformly over the basin and at a uniform rate for a specified duration (D-hours).

Steps to derive UH:

a) A hydrograph plotted by rainfall excess of a given duration (D-h) is selected.

b) Baseflow is separated from the selected hydrograph to derive DRH.

c) The area under the DRH is calculated, which will be equal to the runoff volume.

d) The runoff volume is then divided by the catchment area to obtain effective rainfall.

e) The ordinates of the DRH are divided by the effective rainfall (Obtained from step “d”) to get the ordinates of UH of D-hr duration.

Cl 6.2.3.1

The modulus of elasticity of concrete can be assumed as follows:
E = 5000√f_ck
where
E is the short-term static modulus of elasticity in N/mm².

Actual measured values may differ by ± 20 percent from the values obtained from the above expression.

• The short-term modular ratio is based on the initial tangent modulus, E_C, of the concrete,
• while the long-term modular ratio is based on an effective apparent modulus,
• E_c/k, to account for the effects of creep.
