🌟 𝐕𝐢𝐝𝐞𝐨 𝐒𝐮𝐦𝐦𝐚𝐫𝐲:
In this video, you’ll learn how to calculate the crank length of reinforcement bars (rebars) used in slabs and footings. Cranked bars help maintain effective depth and anchorage—knowing how to compute their extra length is essential in Bar Bending Schedule (BBS) preparation.

✅ 𝐖𝐡𝐚𝐭 𝐘𝐨𝐮’𝐥𝐥 𝐃𝐢𝐬𝐜𝐨𝐯𝐞𝐫:
🔹 What is crank or bent-up bar
🔹 Standard crank angle used in slabs
🔹 Crank Length = Depth / sin(45°)
🔹 When to include or deduct crank length from cutting length

🔥 𝐖𝐡𝐲 𝐓𝐡𝐢𝐬 𝐌𝐚𝐭𝐭𝐞𝐫𝐬:
🌟 Accurate BBS: Avoids extra steel wastage
🌟 Proper Anchorage: Ensures rebar placement is structurally sound
🌟 Standard Practice: Follow IS456 guidelines and site methods

📋 𝐊𝐞𝐲 𝐏𝐨𝐢𝐧𝐭𝐬 𝐈𝐧𝐜𝐥𝐮𝐝𝐞:
🔹 Crank bar used to maintain clear cover in slabs
🔹 Typical crank angle = 45°
🔹 Crank Length (per bend) = Depth / sinθ
🔹 Total Crank Length = 2 × D / sinθ
🔹 Example: For 45°, use 1.414 × D
