Where bars are welded, the most common practice is to provide a square-cut end at the top of the lower bar and a double-beveled end on the bottom of the upper bar. Limits on coating damage—Specify limits on permissi- ble coating damage caused by handling, shipment, and plac- ing operations, and when required, the repair of damaged coating. These types include open stirrups and closed stirrups or stirrup-ties Fig. It should be noted that the amount of offset of the bars is greater for rectangular columns than for round columns. Also, this helps steel fixers and laborers keep track of the type and number of bars needed to complete a certain work.

In detailing offset column bars, a bar diameter plus clearance must be added to the desired offset. Bar Size 6 8 10 12 16 20 25 32 40 Radius m 2. Zinc-coated galvanized bars are identified with a suffix G and a note stating that all bars marked as such are to be zinc-coated galvanized. High- way departments that do not use combination drawings fol- low the procedures of Section 3. Datta has given certain recommendations for the usage of steel in different components of buildings.

This point is important in splic- ing the top bars from the girder to the outside bars in the col- umn. Cutting Length: We must remember than steel is ductile in nature and is subject to elongation. Orientation of reinforcing steel in two-way symmetrical columns shall be shown when reinforcing steel is not two-way symmetrical. Bar supports should be made of dielectric material or wire bar supports should be coated with dielectric material, such as epoxy or vinyl compatible with concrete, for a minimum distance of 2 in. At other locations in the beam, the positive and negative moment strengths shall be equal to or greater than one-fifth the negative moment strength at the face of either joint. Spirals and continuous hoops; 7.

User has the option of manual data entry of each bar or import of batch of bars from Excel. Reinforcing bars for foundations, piers, abutments, wing walls, and slabs are usually shown on plan, section, or eleva- tion views. The special bend defined can be copied, mirrored or stretched etc. There is no standard format for schedules. In continuous beams, the number and spacing of top bars to be placed in T-beam flanges slabs for crack control shall be shown, if so required by the design. For these reasons, final adjust- ments are a field placing problem to suit conditions and toler- ance requirements of a particular job. The maximum spacings permitted are shown in a table in the supporting reference data section.

It should be borne in mind that special precautions such as reducing the speed of bending or increasing the radius of bending may necessary in cold weather. The detailer must show number, mark, and size of members; number, size, and length of straight bars; number, size, mark, and length of bent bars and stirrups; spacing of stirrups; offsets of bars; lap splices; bar supports; and any other special information nec- essary for the proper fabrication and placement of the rein- forcing steel. . The installer should be careful to fabricate the stirrup from one piece of steel and adequately overlap each end. Charges for extras can be added to the base price per hun- dredweight. Note, unless A is small relative to d, this shape is fabricated in a closed form and pulled to shape on site.

This spreadsheet is characterised by its simple and user friendly interface that allows quick input of information in a clear format. Schedules of reinforcing bars are used to divide a structure into parts enabling the fabricator to make it more convenient for the placer by delivering the bars in lots as required. Bar support placing layouts for typical panels are required for two-way reinforcing steel and wherever needed to clarify plac- ing sequence or quantities required. It also defines standard hook Section 7. S1 and S2 should be specified when fabrication after galvanization in- cludes cutting and bending. Bending details can be shown on a separate drawing in- stead of on the placing drawings. It also includes a shape code pop-up window to speed up input process.

Suitable coatings are nylon, epoxy, or vinyl. If the structure is sufficiently large, a separate drawing and bar list is made for each unit. In reinforced-concrete joist floors, there can be so many variations from the basic joists shown on the structural drawings that it is necessary to change the basic designations for example, from prefix J to prefix R, for rib. Only bent bars are given a mark to assist the placer in selecting the proper bars for each member. Bend Length:- The Bend length calculation is different for Cranked bars bent up bars and bends at corners. We have looked at a number of different spreadsheets in the past but none have met our expectations or been supported in such a helpful manner.

This increases faster execution at site and reduces construction time and cost due to less requirement of workers for bar bending.

The placing drawings must be used with the structural draw- ings. Method of measurement of bending dimensions. Sufficient information shall be presented on the structural drawings and in the project spec- ifications to allow detailing of bars at splices and embedment locations without referencing back to the code. Shape Code 67 A See clause 10. The detailer should identify the specified types and show locations where each is to be used. The slope of the inclined portion shall not exceed 1 to 6. It is complete standalone software that eliminates time consuming work of bar data entry, length calculations and dimensions constrains enforcement.
