Bar Bending Schedule (BBS)
JE / AE Exam – Complete Notes + Numericals
📘 Bar Bending Schedule (BBS) क्या है?
Bar Bending Schedule (BBS) एक detailed tabular statement होती है, जिसमें किसी भी RCC structure (जैसे Beam, Column, Slab, Footing) में उपयोग होने वाली steel reinforcement की diameter, length, bend, quantity और weight की पूरी जानकारी दी जाती है।
BBS का उपयोग मुख्य रूप से quantity estimation, cost control और site execution के लिए किया जाता है। JE / AE examinations में BBS से direct theory questions, numericals और MCQs पूछे जाते हैं।
👉 Exam Point:
BBS = Steel Quantity + Shape + Length + Weight
BBS = Steel Quantity + Shape + Length + Weight
🎯 BBS क्यों आवश्यक है?
- Steel की exact quantity निकालने के लिए
- Construction cost control के लिए
- Site पर wastage कम करने के लिए
- Labour productivity बढ़ाने के लिए
- JE / AE exam numericals solve करने के लिए
📐 सबसे महत्वपूर्ण Formula (⭐⭐⭐⭐⭐)
Steel Weight (kg/m) = d² / 162
जहाँ d = bar diameter (mm)
📊 Steel Weight Table (Exam Ready)
| Diameter (mm) | Weight (kg/m) |
|---|---|
| 8 | 0.395 |
| 10 | 0.617 |
| 12 | 0.888 |
| 16 | 1.58 |
| 20 | 2.47 |
🧮 Solved Numerical (JE Level)
Q. 12 mm diameter bar का weight निकालिए।
Solution:
Weight = 12² / 162 = 144 / 162 = 0.888 kg/m
Answer: 0.888 kg/m
Solution:
Weight = 12² / 162 = 144 / 162 = 0.888 kg/m
Answer: 0.888 kg/m
⭐ JE / AE Exam Tips
- Weight formula पूरी तरह याद रखें
- Stirrups numericals बार-बार पूछे जाते हैं
- Shape code से MCQ आते हैं
- Slab steel per sqm question बहुत common है
