Column Buckling During Casting....
What is Column Buckling During Casting?

Column buckling during casting happens when a slender or poorly braced column bends or deforms due to instability under the fresh concrete load or improper shuttering support during the pouring process.

❌ Causes of Column Buckling During Casting:

1. Slender Columns Without Lateral Bracing

Tall and thin columns without temporary supports tend to buckle under wet concrete pressure.

2. Weak or Loose Shuttering

Poor formwork setup allows the column to move or tilt while concrete is being poured.

3. Uncontrolled Concreting Pressure

Fast or uneven concrete pouring creates excessive pressure, causing bending or shifting.

4. Uneven Compaction or Vibration

Over-vibrating or vibrating on one side can displace reinforcement and cause imbalance.

5. Improper Reinforcement Tying

Loose or poorly anchored steel reinforcement lacks stiffness to resist lateral movement.

6. Lack of Horizontal Ties Between Columns

Columns poured without tie beams or bracing at intermediate levels are vulnerable.

✅ Remedies to Prevent Buckling:

1. Use Lateral Bracing (Temporary Supports)

Tie columns to adjacent formwork, scaffolding, or ground using wooden or steel props.

2. Check Shuttering Stability

Ensure formwork is rigid, aligned, and properly supported to resist lateral loads.

3. Pour Concrete in Layers

Pour in 300–450 mm layers and compact evenly to reduce pressure on shuttering.

4. Maintain Plumb Line

Keep checking vertical alignment during casting using a plumb bob or laser level.

5. Proper Steel Tying and Spacers

Ensure all vertical and transverse bars are tied properly and spacers are used.

6. Connect Columns with Beams

Cast columns in stages if necessary, connecting with plinth or tie beams before full height casting.

Bridge vs Culvert - Know the Difference!

As civil engineers, it's crucial to understand where and why we use different structures like bridges and culverts. While they may seem similar, their design, purpose, and construction vary greatly based on site conditions.

• Bridge
- Designed for large water bodies
- Span usually more than 6 meters
- Requires deep & strong foundation
- Carries vehicles and pedestrians

• Culvert
- Suitable for small streams or drains
- Span typically less than 6 meters
- Constructed using simple box/pipe structures
- Usually embedded within road embankments

Choosing the right structure ensures cost-effective, safe, and durable infrastructure solutions.

Zaha Hadid’s Twisting Skyscraper Tops Out in Milan!
The iconic Generali Tower—formerly known as Lo Storto (“The Twisted One”)—has reached its full height of 170 meters. Designed by Zaha Hadid Architects, this striking 44-story skyscraper will house the Generali insurance firm, adding a bold statement to Milan’s skyline.

Once complete, it will stand alongside the Allianz Tower by Arata Isozaki and Andrea Maffei, as well as a future tower by Daniel Libeskind, forming the heart of the transformative CityLife development.

A masterpiece of innovation and design, this architectural marvel is redefining the cityscape. What do you think of Milan’s newest landmark?
