This standard coves wire that is made from cold-worked drawn or rolled deformed wire, or a combination of deformed and non-deformed wires. Stressing sequence for posttensioning tendons. Combining values may result in nonconformance with the specification. We are confident that we have what you are looking for.

The values stated in each system are not exact equivalents; therefore, each system must be adtm independently of the other. Type and location of mechanical and welded splices of reinforcement.

Where sections within Chapters 2 through 7 of ACI are referenced in other chapters and appendices of ACIthe provisions of Sections through of this code shall apply. The size and location of structural elements, reinforcement, and anchors. However, the development length td in inches, measured from the point of the critical section to the outermost cross wire shall not be less than. For splices in columns with offset bars, Fig. A limit of 2. Load ratings up to kN 56, lbf Base lengths up to mm 48 in Various roller 4a97 available Available in 3-point and 4-point configurations.

Minimum ashm compressive strength at time of posttensioning. It shall be permissible to furnish high-strength wire in place of regular wire if mutually agreed to by the purchaser and supplier. Yield strength of welded plain wire fabric shall be considered developed by embedment of two cross wires with the closer cross wire not less than 2 in.

The specified strength or grade or reinforcement. Development of deformed bars and deformed wire in tension.

The magnitude and location or prestressing forces. Development of deformed bars and deformed wire in compression. For staggered splices, the clear spacing is the minimum distance between adjacent splices [distance x Fig. For bars larger than No. Within the text the inch-pound units are shown in brackets. TestResources specializes in test equipment, machines and fixtures that are used in material testing. Therefore, the term “welded wire fabric” has been replaced with the term “welded wire reinforcement” in this specification and in other related specifications.

Combining values from the two systems may result in nonconformance with this specification. A Class B minimum coating thickness is required for wire and welded wire fabric intended for use as reinforcement in earth.

The tolerance for minimum concrete cover of 7. Call our applications engineers to a4977 with an expert in material testing.

ASTM publishes steel/welded wire reinforcement standard.

When using the wire fabric factor from Note 1-Welded wire for concrete reinforcement has been described by various terms: Welded intersections shall not be spaced farther apart than a479 in. The wire reinforcement industry prefers the term “welded wire reinforcement” WWR as being more representative of the range of products being manufactured. When multiple bars located in the same place are spliced at the same section, the clear spacing is the minimum clear distance between the adjacent splices.

We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications. The wire reinforcement industry prefers x497 term “welded wire reinforcement” WWF satm being more representative of the range of products being manufactured.
