Under the state specification for concrete reinforcement, ASTM A is called out. This specification uses deformed steel wire under A Under the. ASTM A/AM [ Withdrawn ]. Standard Specification for Steel Welded Wire Reinforcement, Deformed, for Concrete (Withdrawn ). ASTM A & A TESTING FIXTURE – Application. This testing device is used to determine the shear strength of the welds of welded wire fabric. As it regards.

Welded intersections shall not be spaced farther apart than 12 in. Within the text the inch-pound units are shown in brackets.

For values above 2. Welded intersections shall not be spaced farther apart aetm 16 in. However, the development length asfm in inches, measured from the point of the critical section to the outermost cross wire shall not be less than except that when reinforcement provided is in excess of that required, this length may be reduced in accordance with The values stated in each system are not exact equivalents; therefore, each system must be used a4977 of the other.

Stressing sequence for posttensioning tendons. Anchorage length of reinforcement and location and length of lap splices. Within the text, the inch-pound units are shown in brackets. A Type 1 coating is a fusion-bonded epoxy coating that has been designed to be sufficiently flexible to allow fabrication of the coated wire or welded wire fabric.

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. 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. When q497 the wire fabric factor from Development of deformed bars and deformed wire in tension. The wire reinforcement aa497 prefers the term “welded wire reinforcement” WWF as being more representative of the range of products being manufactured.

Reinforcement shall comply with ACISection 3. It shall be permitted to reduce the development length in accordance with For structures assigned to Seismic Design Category D, E or F, a statement if slab on grade is designed as a structural diaphragm see Section Within the text the inch-pound units are shown in parenthesis.

Therefore, the term “welded wire fabric” has been replaced with the term “welded wire reinforcement” in this specification and in related specifications. The magnitude and location or prestressing forces. Type and location of mechanical and welded splices ast, reinforcement. For staggered splices, the clear spacing is the minimum distance between adjacent splices [distance x Fig.

Combining values from the two systems may result in nonconformance with this specification. When multiple bars located in the same place are spliced at the same section, the clear spacing aztm the minimum clear distance between the adjacent splices. Bends with inside diameter of less than 8db shall not be less than 4db from nearest welded intersection.

The size and location of structural elements, reinforcement, and anchors. A Class A minimum coating thickness is required for wire and welded wire fabric intended for use as reinforcement in concrete and masonry.

Provision for dimensional changes resulting from creep, shrinkage and temperature. 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.

This standard coves wire that is made from cold-worked drawn or rolled deformed wire, or a combination of deformed and non-deformed wires. 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.

It shall be permissible to furnish high-strength wire in place of regular wire if mutually agreed to by the purchaser and the supplier. Within the text the inch-pound units are shown in parentheses.

The tolerance for minimum concrete cover of 7. The development length ld for the specified yield strength fy shall be in accordance with A Type 2 coating is a fusion-bonded epoxy coating that has not been designed to be sufficiently flexible to allow fabrication of the coated wire or welded wire fabric.

It shall be permissible to furnish high-strength wire asfm place of regular wire if mutually agreed to by the purchaser and supplier. The stress in the unspliced reinforcement shall be taken as f y times the ratio of the shortest length embedded beyond the section to l dbut not greater than f y.
