Bending dimensions and scheduling of steel reinforcement for concrete

1 Scope This standard specifies bending dimensions, the methods of measuring bending dimensions and the scheduling of steel bars that are used for the reinforcement of concrete. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. Information on currently valid national and international standards can be obtained from the SABS Standards Division. SANS 920, Steel bars for concrete reinforcement. SANS 1024, Welded steel fabric for reinforcement of concrete. 3 Definitions For the purposes of this document, the following definitions apply. 3.1 bend end portion of a bar, bent through 90° with respect to the adjacent portion of the bar and comprising a length n as shown in figures 2 and 3 3.2 bending schedule list in which the nominal sizes, types of steel, cutting lengths, bending shapes and dimensions of bars are given NOTE Throughout this standard, the diameter of a reinforcing bar is indicated as “d” and the standard radius of bending of such bar as "r". 3.3 calculated length calculated length of a bar, measured along its centre line NOTE Approximate values determined from the formulae given in table 1 are acceptable.

4.1.4 The dimensions for the scheduling of reinforcement bounded by concrete faces shall allow for the appropriate tolerances shown in table 2, plus the tolerances allowed for formwork and concrete cover to reinforcing bars. 4.1.5 To facilitate packing for transportation, each bent bar shall fit inside an imaginary rectangle, of size 18 m × 2,2 m. NOTE 1 Normally the length of a bar should not exceed 13 m, although longer lengths can be obtained by special agreement with the supplier. NOTE 2 Certain bar types are supplied in coils. For helical bars (shape code 86 in table 1), check with the manufacturer as to which steel is available in roll form, i.e. in lengths considerably in excess of 13 m. 4.1.6 The standard values for minimum radii, bend and hook allowances (r, n and h respectively, as given in figures 2 and 3) shall apply to all shape codes, as applicable. If larger values are required, then the bar shall be treated as a "non-standard" bar (code 99) in accordance with 4.2.1.2. Where a non-standard radius is specified (for example, shape codes 51 and 65), it shall be not less than r.

4.2.2 Hooks and bends 4.2.2.1 Unless otherwise stated in a bending schedule, the proportions and dimensions of the hooks and bends shown in column 4 of table 1 shall conform to the appropriate values given in figures 2 or 3, as relevant, subject to variations as may follow from tolerances in other portions of the bar. 4.2.2.2 For all shapes with two or more bends in the same or opposite directions (whether in the same plane or not), the overall dimension given in the schedule shall always include a minimum straight length between the curved portion of the bends, as shown in figure 4. The value of this straight portion shall be not less than the following (see SANS 920): a) 4d for material with characteristic strength of 250 MPa; b) 4d for material with characteristic strength of 450 MPa and not exceeding 20 mm diameter; and c) 6d for material with characteristic strength of 450 MPa.

Figure 4 — Example of bar with more than one bend 4.2.2.3 The overall off-set dimension of a crank shall be not less than twice the diameter of a circle that circumscribes the bar or the wire. The angled length, as shown in figure 1, shall be not less than the following: a) 10d for material with a characteristic strength of 250 MPa; b) 12d for material with a characteristic strength of 450 MPa and not exceeding 20 mm diameter;

and c) 14d for material with a characteristic strength of 450 MPa and exceeding 20 mm diameter. 4.2.2.4 The length of material to be used in the determination of the calculated length to form a bend or hook shall be as given for n or h in figures 2 and 3. 4.2.3 Radii of bends 4.2.3.1 The internal radius of a bend, hook or corner of a bar (where the radius is not specified as r as in table 4 or can be determined from dimensions) should be twice the nominal size of the bar, in the case of hot-rolled mild steel bars, and three times the size of the bar, in the case of high yield stress steel bars and cold-worked steel bars (see figures 2 and 3). Where so desired, the radius for corners may be increased. This change shall be indicated as shape code 99.



19

4.2.3.2 The internal radius of corners marked with a radius r or where the radius can be determined from a dimension, shall be not less than the radius as specified in 4.2.3.1. 4.2.3.3 Corners in non-standard bars shall comply with 4.2.3.1 or 4.2.3.2, as applicable.

4.2.4 Angles 4.2.4.1 Unless otherwise stated in a bending schedule, the angle formed at a bend shall be a right angle. 4.2.4.2 In the case of an angle of a corner that is not a right angle, a) if the overall height is critical, the angle shall be defined by a slope length and an offset, as

shown in figure 1(b), and b) if the slope is critical, the angle shall be defined by the length of the slope and the rise, as shown

in figure 1(a). 4.2.5 Curved bars A bar that has to be formed to a radius less than or equal to the appropriate value given in table 5, shall be bent to the required curvature before being placed in its final position. Reinforcement to be formed to a radius exceeding that given in table 5, shall be supplied straight and the required curvature can be obtained during placing. NOTE 1 For shapes with straight and curved lengths (for example, shape codes 39, 51, 81 and 85 in table 1), the largest practical radius for the production of the continuous curve is 200 mm (this value should be checked with the bending yard concerned) and for larger radii the curve may be produced by a series of short straight sections. NOTE 2 A section of up to 300 mm at each end of a bar cannot be radiused. If necessary, the cutting length should make allowance for these lengths to be removed from the radiused portion.

32 43 NOTE If a larger radius is required, the bar should be supplied as a straight bar and the required radius can be obtained during placing (see also notes to 4.2.5)

5 Bar and fabric schedules 5.1 General NOTE The purpose of the provisions given in this clause is to obtain uniformity in the compilation of bar and fabric schedules. The implementation of these provisions should lead not only to easier interpretation of working drawings but also to simplification of the preparation of a bending and cutting list.



22

5.1.1 The bar and fabric schedules shall be separate and shall be drawn up as shown in tables 3 and 4, respectively. Individual schedules shall be done on A4 sheets, but larger sheets of the A series may be used in such a way that the schedules can be cut or folded to a nominal A4 size. For simple structural components such as beams, columns and rectangular column bases (but not only them), the assembly drawing of the component may be included on the same sheet as the schedule. Such drawings may be produced on A3 sheets on which the width of the schedule should be confined to the nominal width of an A4 sheet. 5.1.2 All hooks, bends and corner radii of bars shown in figures 2 and 3 shall be deemed to be standard values and are not reflected in dimensions in the schedule. For non-standard bars, dimensions of standard hooks, bends and corner radii may be omitted and where so omitted they shall be deemed to be standard values. NOTE For computer produced schedules, the column widths and the size of the schedule may vary from those shown in figure 2 and 3, but the sequence of columns should be maintained. The schedule should not be significantly larger than size A4. 5.1.3 The bar or fabric schedules shall include the statement "This schedule complies with SANS 282". 5.2 Title block The title block shall appear either at the top or at the bottom of the schedule. The following information shall be displayed in the title block: a) the name of the project; b) the number of the project; c) the component type and the location (which shall appear in the title block or elsewhere in the

schedule); d) a cross reference to a layout drawing number; e) the schedule number with an optional revision number. This should appear close to the right-

hand edge of the schedule. If the revision number does not form part of the schedule number, then the revision number shall be shown separately but adjacent to the schedule number;

f) the name of the organization responsible for the design of the project; g) the date the schedule was prepared; h) the signatures or printed initials of the engineer and the checker; and i) such other information as the design organization deems necessary for the adequate control and

administration of the project. NOTE Where a revision of the schedule is necessary, the line or lines affected may be indicated by a suitable reference on the schedule. 5.3 Bar and fabric marks The bar mark given in column 3 of table 3 and the fabric mark given in column 1 of table 4 shall consist of the identifying numbers or letters (or both), that shall also be displayed on a label (see clause 6), which shall be attached to the bars or to the fabric. Bar and fabric marks should consist of a range of consecutive numbers/letters, and no mark should consist of more than three characters.



23

The numbers should be taken from the range 01 to 99 and the letters should be taken from the range A to YY. Where such ranges are inadequate, use either a) a combination of letters taken from the range A to YY, followed by a single-digit number, or b) a combination of numbers taken from the range 01 to 99, preceded or followed by a letter. Combinations starting with "E" shall be reserved for bar marks where special end preparation is required (for example, couplers). 5.4 Type and size In the "type and diameter" column, the types of steel and the nominal sizes of bars (given in SANS 920), shall be indicated in abbreviated (symbol) form, as follows: a) symbols R denotes plain round mild steel bars, of strength 250 MPa; Y denotes high yield deformed steel bars, of strength 450 MPa; and Z denotes types of steel not covered by R or Y; b) sizes: The size of the bar is given after the symbol and indicates the nominal diameter of the bar

in millimetres. NOTE Where possible, mesh may not be listed on the same schedule as bar reinforcement. 5.5 Bending schedule 5.5.1 The bending dimensions given in table 3 and table 4 should be multiples of 5 mm, and due regard should be given to the applicable requirements and bending tolerances in table 2. 5.5.2 Shapes of shape code 99 shall be shown in sufficient detail (see annex A) to facilitate cutting and bending, or they shall be supported by a dimensioned sketch. The method for the measurement of dimensions in table 4 shall be used. The total length shall be given, and unless there is an end anchorage bend or hook, one bending dimension, preferably an end dimension, shall be indicated as the free dimension, to allow for permissible deviations. The r, n and h values, if different from the values given in figure 2 and figure 3, shall be given in the schedule. The tolerances in table 2 also apply to shape code 99. 5.6 Bending of fabric reinforcement 5.6.1 The sketch in column 13 of table 4 shall indicate the following: a) the direction of bending relative to the transverse wires (see figure 5(a));

a) Position of transverse wires
