Special Publications

WWR-400-R:  Bending Welded Wire Reinforcement
1999, 12 pages
A pictorial and descriptive publication on the fabrication of either in-plant or on-site bending of welded wire for column cages, beam baskets, and shear reinforcement for both cast in place and precast/prestressed structural components.

WWR-500:  Manual of Standard Practice--Structural Welded Wire Reinforcement
2006 - Updated 7th Edition, 35 pages                                                     
This manual provides current product information, material specifications, and properties, and lists current ACI 318 Code provisions relating to WWR. Tables and design aids are included on splicing and areas of cross sections for various wire spacings. Two new sections cover testing of wire and welded wire reinforcement, as well as handling and placing guidelines.

WWR-600:  Structural Detailing Manual
2006, 10 chapters have been updated and case studies and tech facts have been included
Members only - Contact a WRI Producer Member
This manual may be used for detailing guidance on welded wire reinforcement in one-way and two-way slabs, precast/prestressed concrete, column & beam detailing, cast-in-place walls, and slabs-on-ground. Sections also cover ACI 318 provisions and shortcuts to compare areas of high strength WWR with areas of mild reinforcing.

Impact of the Seismic Design Provisions of the International Building Code (IBC)
by Dr. S.K. Ghosh, 47 pages (This is not a WRI publication--but WRI has permission to distribute it. WRI is a member of the Alliance for Concrete Codes and Standards (ACCS) which helped fund the publication).
The seismic design provisions of the first (2000) Edition of the IBC represent revolutionary changes from the model codes it was developed to replace - BOCA, UBC, and the SBC. The purpose of this publication is to bring out potential impacts of the seismic design provisions of the 2000 IBC that makes it understandable to a broad audience including design professionals, building and code officials, academics, and others.

A Sample Specification for Welded Wire Reinforcement (WWR)
2006, 6 pages
We have had many requests for an example of a Sample Specification that design and construction professionals may review when preparing their own construction documents. This is a sample specification prepared by an engineer with a WRI member producer. (Please review the WRI Disclaimer attached at the end of the document.)

WRI Tech Facts

TF 203-R-03: Welded Wire Reinforcement ASTM Test Data for Quality Assurance
1998, 2 pages
This Tech Fact contains the current test criteria from all 4 of the ASTM Standards (A82, A496, A185, & A497). It points out required testing that must be performed for all welded wire before it leaves the point of manufacturing. The publication is produced with the permission of ASTM and gives the specifier and user the confidence that the materials have been tested for the required strength and durability that they expect.

TF 207-R-03: Provisions in ACI 318 for Structural Welded Wire Reinforcement
1999, First Printing, 6 pages
This Tech Fact contains key ACI 318 code provisions concerning wire and welded wire reinforcement for reinforced concrete. The reference can be used as a guide for design expressions, approved ASTM material references, and commentary to assist in design and writing specifications. The Tech Fact may be inserted in the WRI Structural Detailing Manual -Section 1- and will be updated as future codes are published.

TF 208-R-08:  (D) Structural High Strength Welded Wire Reinforcement - Current Product Knowledge
2008, 3rd Printing, 7 pages
This Tech Fact describes current manufacturing abilities, applicable specifications and nomenclature, handling and unloading, placing to obtain proper positioning, coated WWR, and metrication. Tables are included to make it easier for converting units and knowing what common styles are produced and determining areas of steel for various wire spacings.

TF 209-R-08: Design Aids For Structural Welded Wire Reinforcement (includes WWR/Rebar Comparison Tables)
2008, 2nd Printing, 14 pages
This issue contains lists of ASTM & AASHTO Standards that apply to wire and WWR. Also ASTM physical properties for minimum yield and tensile strengths and minimum weld shear strength criteria. There are examples using the included 4 sets of tables. The tables compare various spacings of rebar at 60 ksi yield strength with various spacings of WWR at 60, 70, 75, and 80 ksi yield strengths.

TF 209-R-08 Metric: Design Aids For Structural Welded Wire Reinforcement (includes WWR/Rebar Comparison Tables)
2008, 2nd Printing, 14 pages
This issue is a metric-centered version of TF 209-R-08.

TF 702-R-08: Supports Are Needed for Long-Term Performance of Welded Wire Reinforcement In Slabs-On-Grade
Updated 2008, 6 pages
The questions of "why" and "where" supports are necessary are covered in this publication. Types of supports for WWR and the influence of the sub base conditions on their selection are addressed. Suggested spacings of supports are furnished to show the different spacings when wide spaced WWR (step-through styles) is specified vs. the smaller spaced styles.

TF 703-R-03: Synthetic and Steel Fibers Are Not Concrete Reinforcement
1995, 2 pages
This Tech Fact illustrates which codes and guides specify WWR and that none recognize any form of fibers as concrete reinforcement. The publication focuses on ettringite and alkali-silica phenomena causing cracking which makes the use of steel reinforcement necessary. A historical performance of an Iowa paving project proved the effectiveness of reinforced concrete over unreinforced concrete.

TF 704-R-03: High Strength Welded Wire Reinforcement Compared with Rebar
1995, 2 pages
This Tech Fact shows an actual distribution facility project that saved considerable costs on the placing of WWR compared with rebar. The high strength WWR saved material costs alone to convince the owner and contractor to use WWR. The contractor's statements give credence to the importance and viability of the use of WWR over rebar in concrete paving, parking lots, and slabs-on-ground.

TF 705-R-03:  Innovative Ways to Reinforce Slabs-on-Ground
1996, 8 pages, by Robert B. Anderson, P.E.
There are five design procedures with examples developed by Mr. Anderson, a leading consultant on the subject of reinforced concrete slabs-on-ground. The publication has derivations of equations and design examples that show how as steel area increases more crack width control is gained. The sub grade drag theory is explained here in more detail, emphasizing the procedure for residential and light commercial projects. The other four procedures should be used for various structural applications where wheel loads and rack loads play a greater role in the design of the slab. There is a table of cross-sectional areas and weights for different spacings of wire (from 3" to 16").
