👉What is the main difference between square column and circular column? Which one is more used and why?

■ Here are some thoughts:

Circular columns are symmetric about any centroidal axis. Square columns have only 4 axes of symmetry.
If you compare a square column with a circular column having the same diameter as the side of the square column, circular column has a smaller cross section area (0.785 times the square column) but larger second moment of area (1.178 times the square column). Thus, it is less prone to buckling and may require slightly more reinforcement to carry the same load as a square column.
The minimum number of bars required in a square column is 4, while for circular columns, it is 6.
Form work for square columns is simpler (due to the straight sides) compared to circular columns.
Circular columns are considered aesthetically pleasing compared to square columns .

Which column gives good strength circular or rectangular??

■ Theoretically, circular columns give more strength compared to rectangular columns.

Consider a circular and a rectangular column of side D, D*B. The cross-sectional area of the circular column will be higher when compared to rectangular columns. Also, the moment of interia of the circular columns will be much higher than that of the rectangular/square columns. Thereby, less dangerous towards buckling.

( The reason to prefer a rectangular column is because it fits with the wall and beam properly. And formwork and compaction are easy)

Even in terms of reinforcement,

The minimum number of bars in the rectangular column is 4.

The minimum number of bars in a circular column is 6.

■ The round or circular columns give more strength with respect to rectangular cross section because of its resistance against buckling and torsion. This is due to its uniform cross-section and high moment of inertia.

Within circular columns, the one with helical stirrups provides 5% more strength in comparison to normal circular stirrups as per IS 456 :2000 (Cl. 39.4).

Generally, rectangular columns are used at the site because:

The ease with which their shuttering is available and used at site..
At the corners, circular columns are difficult to hide. Hence, it causes hindrance in aesthetics.
Problem of binding stirrups (in case of helical it is more difficult).

■The following points show the difference between the strength of two different types of columns,

Due to their Slenderness ratios.
Circular cross-section columns are more resistant to buckling as compared to the rectangular cross-section. Furthermore, circular sections will have uniform torsion characteristics.
No weak corners in circular columns and no stress concentration.
Columns having shear reinforcement in the form of spirals gives better confinement than shear reinforcement in the form of ties.
A column is only as strong as its weakest point, and square columns have four lines of weakness – the folds. The circular cross section doesn't have any folds, so they don’t have any points of weakness and can spread the load they’re bearing out evenly across the whole cylinder.
The resistance to bending or deflection of a circular cross section is higher than a rectangular cross section with the same area. In addition, the load required to buckle a column with a circular cross section is the same around its perimeter, but a beam with a rectangular cross section may bend first in either of two axes.

🔹 Understanding the Contractor’s Delay Claims Process with FIDIC 2017 🔹

In construction, delays are often unavoidable. According to the 2017 FIDIC Red Book, contractors can submit claims for additional payment or time extensions if they encounter delays caused by the employer. Here’s a breakdown of the process:

1- Identify the Delay Event: Recognize any event impacting the critical path and compare the original and actual schedules.

2- Determine Entitlement: Verify if the delay is excusable or compensable based on contract terms.

3- Submit Notice of Claim: Submit a notice within 28 days of the delay event to maintain eligibility for compensation.

4- Engineer’s Initial Response: The engineer has 14 days to respond to the claim with their preliminary assessment.

5- Fully Detailed Claim: Submit a comprehensive claim with all supporting documents within 84 days.

Also helps contractors manage delays professionally, ensuring clarity and compliance with FIDIC standards.

👉Plumb Bob (ቱምቢ)

💫A plumb bob, plumb bob level, or plummet, is a weight, usually with a pointed tip on the bottom, suspended from a string and used as a vertical reference line, or plumb-line.

It is a precursor to the spirit level and used to establish a vertical datum.

It is typically made of stone, wood, or lead, but can also be made of other metals.

The instrument has been used since at least the time of ancient Egypt to ensure that constructions are "plumb", or vertical.

It is also used in surveying, to establish the nadir with respect to gravity of a point in space.

It is used with a variety of instruments (including levels, theodolites, and steel tapes) to set the instrument exactly over a fixed survey marker or to transcribe positions onto the ground for placing a marker.

👉COMPONENTS OF A BRIDGE

🏷What is a bridge ?

⏺A bridge is a structure constructed along a traffic crossing or over obstacles such as river, to make movement of vehicles easier.

⭐️COMPONENTS

▶️The bridge components can basically be divided into two parts or discuss under two headings

🚧A. Sub - structure components

🚧b. Super - structure components

💫Sub - structure are the components below the bearing , on the other hand, components above the bearings constitutes superstructure.

⏺There are various types of bridge being constructed as a result of the technological developments, hence the components of each bridge solely depends on the type of construction made, but the major components for a convectional type of bridge are:

a. Abutments
b. Wing walls
c. Piers
d. Pier cap
e. Bearing
f.  Foundation

❇️1. ABUTMENTS:  Bridge abutments are vertical supports at the bridge ends.

⏺They are the end points of a bridge components which acts as a retaining walls in resist earth pressure in the approach areas .

❇️2. WING WALLS : wing walls are located very close to the abutments.

⏺They are act as a retaining walls in resisting earth in the approach areas.

❇️3. PIER:  This part of the bridge components are vertical supports provided between bridge span.

⏺Their main function is to transfer the loads coming on the superstructure to the foundation.

❇️4. FOUNDATION: Foundation is the key element of a bridge components.

⏺The function of any foundation is to transmit to the subsoil the loads of the structure.

⏺Similarly, the function of the bridge foundation is to transfer the loads coming on substructure and superstructure to a large area and hard strata.

❇️5. BEARING: Bridge bearings are components of the bridge that provides a resting surface between the bridge piers and the bridge deck.

⏺The main function of the bearing is to control movements and reduce the stress involved.

❇️6. DECKING: A bridge decking forms the surface for traffic, it is supported by beams and girders.

👉Why Do Concrete Cracks Occur?

💫The causes of cracking in concrete can be summarized as follows:

1. Thermal Expansion and Contraction: Concrete expands and shrinks in response to temperature changes.

2. Excessive Heat of Hydration: High temperatures during the curing process can lead to cracking.

3. Delayed Curing: Postponing the curing process can weaken the concrete.

4. Improper Casting: Issues during the casting process can contribute to cracks.

5. Settlement of the Structure: Natural settling can create stress, leading to cracks.

6. Heavy Loads: Excessive weight placed on the concrete can cause it to crack.

7. Water Loss: Shrinkage occurs when water evaporates from the surface of the concrete.

8. Insufficient Vibration: Lack of proper vibration during placement can result in air pockets and weak spots.

9. Inadequate Cover for Reinforcement: Insufficient coverage of reinforcement can result in damage.

10. High Water-Cement Ratio: A higher ratio can increase workability but also raises the likelihood of shrinkage.

11. Corrosion of Reinforcement Steel: Rusting steel can expand and crack the surrounding concrete.

12. Rapid-Setting Mixtures: Some fast-setting options have a higher potential for shrinkage.

13. On-Site Water Addition: Adding water after mixing can negatively alter the concrete's composition.

14. Admixture Overdosage: Excessive use of admixtures can adversely affect concrete performance.

15. Incorrect Admixtures: Using the wrong type of admixture can lead to problems.

16. High Temperatures: Elevated temperatures can accelerate curing and increase the risk of cracking.

17. Low-Quality Cement: Poor-quality materials can compromise the integrity of the concrete.

18. High Absorption of Aggregates: Aggregates that absorb too much water can disrupt the balance of the mix.

19. Improper Mix Design: Errors in mix design can lead to inadequate strength and durability.

20. Issues with mass concrete include casting delays, hydration-induced overheating, temperature differentials, unmonitored temperatures, and inadequate insulation that fails to meet requirements. Other concerns involve the full use of cement without pozzolanic material substitutes.

🏷By addressing these factors, the likelihood of cracking in concrete can be significantly reduced.
