if the bar length is 5o m , what will be the actual length including lap length
A bar bending schedule (BBS) is a detailed list of all the reinforcement bars (rebars) required for a concrete structure. It provides information about the size, type, shape, length, quantity, and bending details of each bar. The purpose of a BBS is to help engineers, fabricators, and contractors accurately estimate, cut, bend, and place the steel reinforcement at the construction site. In civil engineering, a BBS is essential for planning and managing reinforcement work. It ensures that the right amount of steel is ordered and that bars are prepared according to design. A good bar bending schedule reduces material wastage, speeds up construction, and helps maintain quality and safety standards. Typically, a BBS includes: Bar mark numbers Bar diameters Shapes and bending details (often shown using codes or diagrams) Lengths of bars, including allowances for bends and hooks Quantities for each type of bar Silicon Engineering Consultants provides bar bending schedule and rebar detailing services that help construction teams work more efficiently and avoid costly errors.
cutting length depends upon the beam length. its including L in both sides
It is a list of reinforcing for the works to be carried out, it lists location of the bar, bar mark, diameter of bar, number of pieces, length before bending, shape code and various lengths of the bent shape to show the maker where to bend It The schedule along with the steel drawing allows the workers to install the steel correctly.
What is a bar bending schedule? A BBS lists the type, size, shape, quantity, cutting length, and bending details of each rebar needed for a structure. It helps with material estimation, ordering, and cutting. 📌 Steps to estimate a BBS ✅ 1️⃣ Study structural drawings carefully Identify all reinforced concrete elements (e.g., beams, columns, slabs, footings) and note bar sizes, spacing, and bar shapes. ✅ 2️⃣ Count and list each bar type Note the number of longitudinal bars, stirrups, ties, spirals, or mesh reinforcement for each element. ✅ 3️⃣ Measure bar lengths Measure the actual lengths on drawings or use formulas: For straight bars: clear length + bends/hooks + anchorage/dev. length For stirrups/ties: perimeter of shape + hooks + allowances For spirals: number of turns × (π × diameter) ✅ 4️⃣ Add standard allowances Include extra for bends, hooks, laps, and wastage (typically ~3-5%). Silicon Engineering Consultants offers bar bending schedule services that provide accurate, ready-to-use schedules for projects of all sizes.
They are the dimensions of each side of the bent steel, added together (taking in to account lost length due to the bends) they tell the bar maker what total length to start with.
This is an incorrect approach. The current method is the reason for the steel wastage. The steel saving is left to the hands of Bar Benders and site engineers.A scientifically proven system, to save steel in the construction projects is the need of the hour.Steel saving starts with the Rebar Detailed engineering. This is also called as Rebar Detailing. A professional Rebar Placing drawing and an optimized Bar Bending schedule (BBS) are the targeted output of the Rebar detailing.
ROD is used for axial loading and torsion, but BAR can be used for axial, torsion as well as bending loads....
