Image mein 3 types ke columns dikhaye gaye hain:
✔️ Rectangular Column (with ties)
✔️ Circular Column (with spiral reinforcement)
✔️ Square Column (with ties)
📌 Sabse strong kaun sa hota hai?
👉 Circular Column (Spiral Reinforcement) sabse strong mana jata hai 💪
📌 Reason:
✔️ Spiral reinforcement poore column ko uniformly confine karta hai
✔️ Load evenly distribute hota hai
✔️ Earthquake resistance zyada hoti hai
✔️ Failure sudden nahi hota (ductile behavior hota hai)
📌 Rectangular & Square Column:
✔️ Inme ties use hote hain
✔️ Load corners par zyada concentrate hota hai
✔️ Confinement spiral ke comparison mein kam hota hai
📌 Conclusion:
👉 Spiral (circular) column = Best strength & safety
👉 Square/rectangular = Normal buildings ke liye common use
👉 Civil engineering ke exams aur practical site knowledge ke liye ye concept bahut important hai.
