The larger size bars, which are more difficult to spring into desired position, are ordinarily employed in massive structures where placing tolerances are correspondingly larger. The straight bar size and length 2. Bars shown as open circles may be accommodated provided clear spaces between bars do not exceed 6 in. Bar support placing layouts for typical panels are required for two-way reinforcing steel and wherever needed to clarify placing sequence or quantities required.

Truss bar dimensioning is special and is shown in large-scale detail in Fig. Open to the public ; R Tie patterns shown may accomodate additional single bars between tied groups provided clear spaces between bars do not exceed 6 in. All sheets in any one set of drawings should be the same size.

Errata are not included for collections or sets of documents such as the ACI Collection. These bars must extend the minimum distance required for lap splices. Enter the email address you signed up with and we’ll email you a reset link. Method of splicing shall always be defined tion.

All bars should appear at least once in a plan or elevation view and in a sectional view, or both. Bar cutoff details must be verified to provide required development of reinforcement.

Dowels, preferably, should be detailed with that portion of the structure where concrete is placed first. Continuous column strip bottom reinforcing steel shall be not less than one-third of the total column strip top reinforcement at the support.

Provides coated bars if specified; slabs in schedules. Coupling sleeve—Nonthreaded device fitting over the ends of two reinforcing bars for the eventual purpose of providing transfer of either axial compression or axial tension or both from one bar to the other.

Bars to be spliced by noncontact lap splices in flexural members shall not be spaced transversely more than the smaller of one-fifth the length of lap and 6 in.

Except for single span slabs where top steel is unlikely to receive construction traffic, top bars lighter than No. If a mechanical or welded splice is to be used, a physical description must be provided.

Bar supports will be furnished by the reinforcing-steel supplier for bottom bars in grade beams or slabs on ground and for the bars in singly reinforced slabs on ground only if specifically required in the contract documents.

Bar placing subcontractor—A contractor or subcontractor who handles and places reinforcement and bar supports, often colloquially referred to as a bar placer or placer.

The equipment can also produce the shipping tags and all manifest documents. Values of tension ld and tension lap splice lengths in the acj are based on the provisions in ACI Combining inch-pound and hard metric values can result in nonconformance with the standard. These bars must extend the ing the lap splice length equal to one spacing of cross wires minimum distance required for lap zci. Special preparation of the ends of the vertical bars is usually required for butt splices. The reinforcing bar placing drawings need only show, and the fabricator will only be responsible to supply, those side form spacers that are equal to the standard bar supports referred to in Section 5.

In detailing offset column bars, a bar diameter plus clearance must be added to the desired offset. Bending details reinforcing steel is detailed, fabricated, and delivered by may be separate or incorporated in the schedule.
