🏗️ ACI 318 — | Deflection & Story Drift
In this part, we learn the difference between total lateral displacement, story drift, and drift ratio in reinforced-concrete shear walls.
📐 Key concepts:
• Lateral Deflection
• Story Drift
• Interstory Drift Ratio
• Building Displacement
• Seismic Performance
🔹 Story Drift = Difference between adjacent-floor displacements
🔹 Drift Ratio = Story Drift ÷ Story Height
Understanding drift is essential for evaluating the seismic behavior and serviceability of a

👉RCC Isolated Column Footing – Reinforcement Details
An RCC isolated column footing (pad footing) is designed to safely transfer the column load to the supporting soil while controlling bearing pressure, bending, shear, and settlement.
🚥Key Components
1. Column reinforcement – Vertical bars transfer column loads into the footing.
2. Pedestal – Provided where required to support the column and improve load transfer.
3. Top reinforcement – Distribution reinforcement as required by structural design.
4. Bottom reinforcement – Main footing reinforcement, generally placed near the bottom.
5. Lateral ties / edge bars – Help maintain reinforcement arrangement and provide confinement where detailed.
6. Cover blocks – Maintain the specified concrete cover.
7. PCC levelling course – Provides a clean and level base below the footing.
8. Brick/block edge shuttering – Temporary/permanent edge restraint where appropriate.
9. Compacted soil – Prepared and compacted foundation subgrade.
Important Construction Points
Reinforcement bar diameter and spacing must follow the structural drawings.
Maintain the specified concrete cover; the illustration shows 50 mm as a typical footing value.
Use proper cover blocks/chairs rather than placing reinforcement directly on PCC or soil.
Provide adequate development length and anchorage for column and footing reinforcement.
Column ties should have the required hooks and spacing according to the applicable design standard.
PCC provides a clean, level working surface; it is not a substitute for structural footing concrete.
Check footing dimensions, thickness, reinforcement, punching shear, one-way shear, and soil bearing capacity before construction.
Concrete grade, reinforcement grade, footing size, and reinforcement spacing must be determined by structural design and the applicable local code.
Note: The values shown in the poster are typical/reference values only.
Actual footing dimensions, reinforcement, cover, concrete grade, and bar spacing must be based on structural calculations, soil conditions, loads, and the applicable design code.

🔹 Honeycombing
🔹 Cracking
🔹 Segregation
🔹 Bleeding
🔹 Poor compaction
🔹 Cold joints
🔹 Poor curing
📌 Important: The cause should be identified before deciding on a repair method.

🚧Road Construction – Surveying, Setting Out & Earthworks
Road construction begins with accurate surveying and setting out, followed by proper earthwork, grading, drainage, pavement-layer construction, and compaction.
Each stage must be controlled to achieve the required alignment, levels, crossfall, and pavement performance.
Key elements shown:
1. Centerline Stake – Establishes the road alignment and chainage reference.
2. Staff / Leveling Rod – Used with a level instrument for taking accurate elevation readings.
3. Auto Level – Determines differences in elevation and helps establish design levels.
4. Grading & Leveling – A grader or dozer shapes the formation to the required profile.
5. Sub-base Layer – Granular material placed and compacted over the prepared subgrade.
6. Base Layer – Stronger granular pavement layer supporting the surface course.
7. Side Drain – Provides drainage and prevents water accumulation within the pavement and formation.
8. Compaction – Rollers compact soil and pavement materials to achieve the specified density.
📐 Typical Road Cross-Section
A typical pavement structure may consist of:
Natural ground
Compacted subgrade
Granular sub-base
Base course
Surface course
Shoulders
Camber/crossfall for drainage
📍 Setting-Out Procedure
1. Study drawings and alignment data.
2. Establish benchmarks and reference points.
3. Set out the centerline and chainages.
4. Take level readings and establish formation levels.
5. Check cross-sections and road width.
6. Proceed with earthwork, compaction, and pavement layers.
7. Carry out continuous quality and level checks.
Important: Actual layer thicknesses, materials, compaction requirements, camber, drainage dimensions, and design levels should be determined from the approved road design, geotechnical investigation, specifications, and applicable standards.

2. Staff / Leveling Rod – Used with a level instrument for taking accurate elevation readings.
3. Auto Level – Determines differences in elevation and helps establish design levels.
4. Grading & Leveling – A grader or dozer shapes the formation to the required profile.
5. Sub-base Layer – Granular material placed and compacted over the prepared subgrade.
6. Base Layer – Stronger granular pavement layer supporting the surface course.
7. Side Drain – Provides drainage and prevents water accumulation within the pavement and formation.
8. Compaction – Rollers compact soil and pavement materials to achieve the specified density.
📐 Typical Road Cross-Section
A typical pavement structure may consist of:
Natural ground
Compacted subgrade
Granular sub-base
Base course
Surface course
Shoulders
Camber/crossfall for drainage
📍 Setting-Out Procedure
1. Study drawings and alignment data.
2. Establish benchmarks and reference points.
3. Set out the centerline and chainages.
4. Take level readings and establish formation levels.
5. Check cross-sections and road width.
6. Proceed with earthwork, compaction, and pavement layers.
7. Carry out continuous quality and level checks.
Important: Actual layer thicknesses, materials, compaction requirements, camber, drainage dimensions, and design levels should be determined from the approved road design, geotechnical investigation, specifications, and applicable standards.

👉SOIL BEARING CAPACITY CALCULATION
🚥Terzaghi Bearing Capacity Method – Study Note
1. What is Soil Bearing Capacity?
Soil bearing capacity is the maximum pressure that soil can safely support from a foundation without unacceptable shear failure or excessive settlement.
2. Terzaghi’s Bearing Capacity Equation
qᵤ = cN꜀ + γDᶠNq + 0.5γBNᵧ
Where:
qᵤ = ultimate bearing capacity (kN/m²)
c = soil cohesion (kN/m²)
γ = unit weight of soil (kN/m³)
Dᶠ = depth of foundation (m)
B = width of footing (m)
N꜀, Nq, Nᵧ = bearing-capacity factors, mainly dependent on the soil friction angle φ
3. Example Calculation – Square Footing
Given:
Cohesion, c = 20 kN/m²
Unit weight, γ = 18 kN/m³
Foundation depth, Dᶠ = 1.5 m
Footing width, B = 2.0 m
Angle of internal friction, φ = 30°
Factor of Safety = 3
For φ = 30° (illustrative values): N꜀ = 30.14, Nq = 18.40, Nᵧ = 16.02
For a square footing:
qᵤ = 1.3cN꜀ + γDᶠNq + 0.4γBNᵧ
qᵤ = 1.3(20)(30.14) + (18)(1.5)(18.40) + 0.4(18)(2.0)(16.02)
qᵤ = 783.64 + 496.80 + 230.38
qᵤ ≈ 1,510.82 kN/m²
4. Allowable Bearing Capacity
Allowable bearing capacity is obtained by applying an appropriate factor of safety:
qₐₗₗ = qᵤ / F.S.
qₐₗₗ = 1,510.82 / 3 ≈ 503.61 kN/m²
Allowable bearing capacity ≈ 504 kN/m²
5. Important Points
Use soil properties obtained from a proper geotechnical investigation.
Bearing-capacity factors depend on the soil friction angle φ and the selected theory.
Footing shape affects the bearing-capacity equation through shape factors.
A suitable factor of safety must be selected according to the applicable design code and project requirements.
Bearing capacity and settlement are separate checks; both must be considered in foundation design.
Groundwater conditions, foundation depth, eccentricity, inclination, and nearby loads may affect the final design.
6. Design Reminder
The numerical example is for educational illustration. Actual foundation design should be based on site-specific soil investigation, structural loads, groundwater conditions, settlement analysis, and the applicable foundation design code.
