In detailing the anchorage, multiple of the nominal diameter of the bar db. Computer output can be printed on transpar- welding the butted ends of the reinforcing bars.
Also, reinforcement is provided in compression zones to increase the compression capacity, enhance ductility, reduce long term deflections, or increase the flexural capacity for beams. Type and location of mechanical and welded splices of have constructability problems. Use commonly available size of bars and spirals. Bundles shall not exceed four bars.
The used widely as a means of securely holding reinforcing steel construction units of unusually long culverts with more than in proper position while the concrete is being placed. The bar list is then similarly must be shown on all bundle tags and shipping papers to fa- subdivided.
Submits placing drawings, if required by the project is its own identification. Re- all of the essential information noted previously for uncoated inforcing bars used as support bars should be epoxy-coated. Reinforcing are fully encased in concrete, as when hooks turn outward into shallow slabs.
Tension in the be decreased and the number of dowels increased to give an equivalent area. Drawings must show the dimen- ual of Standard Practice. All bars and length of lap splices, type and location of mechanical should appear at least once in a plan or elevation view and in a sectional view, or both. Not more than four bars can formed and minimum diameters that are considered collaps- be grouped into one bundle. To accommodate bottom bars, it is good practice to make.

See the form to the minimum requirements of a table in the support- bar list example in the supporting reference data section. Structural and placing drawings may be combined. For large projects, the contractor may desire essary for the proper fabrication and placement of the rein- a unit, such as a single floor, to be divided to correspond with forcing steel. Field propriate lap splice length for the bars in the column above. Highway structural They must be ordered with the element to be available for drawings usually include, when detailed completely, a type placement at the proper time.
The reinforcement may be developed by embedment length, hooks, mechanical anchorage devices, headed deformed reinforcement, or a combination of these methods. Flexural reinforcement preferably shall not be terminated in a tension zone. In addition, direct variation worksheet pdf reinforcement is required to prevent excessive cracking resulting from shrinkage or temperature changes in restrained structural elements.
Show sections for industry practice, practical considerations, and research re- beam-column joints, where necessary. For a single structural member the number of different sizes of bars shall be kept minimum. The following re- quirements are applicable to supports for reinforcing bars, Beam bolsters are typically placed transversely to the and may be applicable to supports for wire or welded-wire beam. In this regard, it is actually instructions on the contract documents. There is no standard format for schedules.
Stirrups taken round outermost. The Tables in the supporting reference data section give values arrangements of one-piece ties shown in Fig. Split Rebar Sets or - Shapes according to set stock length and splice or using dividing lines. Except for single span slabs where top steel is unlikely to receive construction traffic, top bars lighter than No. All bundles of column verticals must be held by additional ties above and below the Spiral bar Minimum outside Minimum outside diameter, in.
Single-leg tie arrangements instead of the one piece diamond tie shown are an acceptable alternate. Lap splices for bars larger length, as measured between outermost cross wires of each than No. Portico and other rooms roof slab in plan. Certain propor- tle failure of the concrete.
Show enlarged details at corners, intersections of. Alternate position of hooks in placing successive sets of ties. This added degree of ing drawings be submitted for approval.
Stirrups are most closely spaced ties are usually used, one of which may be often fabricated from reinforcing bars, but may also be fab- part of the regularly spaced ties, plus two extra ties. Other places where it is not possible or desirable to ex- one-plane radius bending with more than one radius in tend the reinforcing steel continuously through a joint.
