BS8666 is the British Standard rebar shape code list required to be adhered to when using steel to reinforce concrete in construction in the United Kingdom and Northern Ireland. The latest update, BS8666:2020 (from BS8666:2005) updates the standard more closely inline with BS EN 1992-1-1 Eurocode 2 (which you can download for free here ). Bar Bending Shape Codes As Per BS 8666:2005 Different bar bending shaped codes are listed below. Where L = Total length of the bar Minimum Scheduling Radius, Diameter And Bend Allowance: 6 mm, 8mm and 50 mm are non preferred sizes available to special order. Happy Learning. Share this: Telegram
Different Shapes of Reinforcing Bars
The list below shows the various bar bending shape codes: Shape Code 00 to 34 Shape Code 35 to 98 Spread the love Tags: bbs codes, reinforcement shape codes About The Author John Steffen I love to share my experience on civil engineering and construction estimates. However, a typical BBS schedule section contains 10 columns in the following order: [1] MEMBER: This shows the particular member in consideration.E.g base type 1, base type 2, column type 1, column type 2 etc [2] BAR MARK: This depicts different bar marks present in the drawing.E.g. 01, 02, 03 etc. [3] TYPE and SIZE: Type relates to whether the specified reinforcement is of high or mild yield. Bar Markings There are a number of ways to identify reinforcing bar (rebar) from the production mill to the fabrication shop to the jobsite. This documentation and marking system helps provide a wealth of useful information about the manufacturing and composition of each bar of reinforcing steel.

Bar Mark is the identifying mark against each unique bar type in a drawing which refers to individual entries on the BBS. The same number is mentioned in the delivery label. A new number must be used if when the cross-section or shape or the length of bend is different. Shape code is a two-digit code which refers to the reinforcement bending shape. Shape Code Shape Diagram Total Length of Bar, L measured along centre line 22 A+B+C+(D)-1.5r-3d semi-circular (D) New C shall not be less than 2(r+d). Neither A nor (D) shall be less than P in Table 2. D shall not be less than C/2+5d. 23 A+B+(C)-r-2d effective cross-sectional area of the bar or wire, sometimes referred to as size 3.4 bar (or fabric) mark identifying mark which cross-refers individual line entries on the schedule to the detailed drawing NOTE The bar (or fabric) mark also appears on the delivery label. 3.5 shape code two-digit coded designation of the reinforcement shape NOTE. 6. The label of bar mark reference attached to the bundle bar must relate uniquely to an appropriate set or group of bars of defined shape, size, length, and type used in the work. Information on the bar schedule sheet. Member: The location in which the bar is used. Bar mark: the number of the bar in its sequence in the detail drawing.

When calculating the reinforcement detailing for different members for a building, taking account of small bent ups and other angle detailing will make the difference of effective and economic BBS.
BS 4466: 1989 Shape Codes In April 2000 a new British Standard, BS8666 the 'Specification for scheduling, dimensioning, bending and cutting of steel reinforcement for concrete' was introduced, replacing BS 4466. Although BS4466 is superseded it is still used and is described below for reference purposes. BS 4466 - Non Preferred Shapes Notes These Rebar Shapes don't contain these Shape Images, to make it possible for you as a user to customize this. For rebar schedule representations during demos of "Rebar with Revit", my colleague Dieter edited the default rebar shape families and added the shape code images according to BS8666 : 2005, to the Shape Image parameter.

Note 2 For shapes with straight and curved lengths (e.g. shape codes 12, 13, 22 and 33) the largest practical radius for the production of a continuous curve is 200mm, and for larger radii the curve may be produced by a series of short straight sections.
