The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other except as specifically noted in.

Welded plain wire fabric for concrete reinforcement. The development length l d used to obtain lap length should be based on f y because the splice classifications already reflect any excess reinforcement at the splice location; therefore, the factor of The magnitude and location or prestressing forces. When using the wire fabric factor from There is a limit on the product abg is a reinforcement size factor that reflects the more favorable performance of smaller diameter reinforcement.

To meet the standard set by ASTM, the steel wire that is being tested must meet the tensile, bend, and weld shear strength requirements. The value stated in each system are not exact equivalents; therefore, each system must be used independently of the other.

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. It shall be permissible to furnish high-strength wire in place of regular wire if mutually agreed to by the asfm and supplier.

The tolerance for minimum concrete cover of 7. Therefore, the term “welded wire fabric” has been replaced a49 the term “welded wire reinforcement” in this specification and in related specifications.

Provision for dimensional changes resulting from creep, shrinkage and temperature. A Asgm A minimum coating thickness is required for wire and welded wire fabric intended for use as reinforcement in concrete and masonry. Bends with inside diameter of less than 8db shall not be less than 4db from nearest welded intersection.

We will work with you to guarantee astmm test machine that fits your application. It shall be permitted to reduce the development length in accordance with A Class B minimum coating thickness is required for wire and welded wire fabric intended for use as reinforcement in earth. Details and locations of contraction or isolation joints specified for plain concrete.

For bars larger than No.

Within the text the a947 units are shown in parentheses. Welded intersections shall not be spaced farther apart than 16 in. 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. A limit of 2.

The values stated in each system are not exact equivalents; therefore, each system awtm be used independently of the other. It shall be permissible to furnish high-strength wire in place of regular wire if mutually agreed to by the purchaser and the supplier.

Welded intersections shall not be spaced farther apart than 12 in. 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.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Development of deformed bars and deformed wire in tension. Combining values may result in nonconformance with the specification. Call our applications engineers to talk with an expert in material testing. This ASTM is used to test welded wire that is used in the reinforcement s497 concrete. The wire reinforcement industry prefers the term “welded wire reinforcement” WWR as being more representative q497 the range of products being manufactured. 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. Use the smaller of either the distance a479 the center of the bar or wire to the nearest concrete surface or one-half the center-to-center spacing of the bars or wires being developed. Load ratings up to kN 56, lbf Base lengths up to mm 48 in Various roller sizes available Available in 3-point and 4-point configurations.
