Preface
This is the third edition of CSA Standard W186, Welding of Reinforcing Bars in Reinforced Concrete Construction. It is written in SI (metric) units and replaces the previous editions published in 1981 and in 1970.
Extensive revisions have been made to several Clauses, some of which have been deleted and new ones added. The Committee revised the Appendices and has updated the various examples given for guidance in design.
The revisions were made to reflect the experience and knowledge gained during recent years.
An important consideration was to ensure that this Standard continues to relate completely to the Limit States (Load Factor) Design.
This Standard was prepared by the Technical Committee on Welding of Reinforcing Bars under the jurisdiction of the Standards Steering Committee on Welding, and was formally approved by these Committees.
Scope
1.1
This Standard applies to
(a) the design, fabrication, and inspection of welded connections utilizing deformed reinforcing bars and to the certification of companies involved in such work;
(b) welding of deformed reinforcing bars (except for pre-stressing steel or for bar or rod mats for which the welding is covered by the manufacturing specification) either directly to each other or through splice members; and
(c) welding of deformed reinforcing bars to structural steel members used as anchorages in precast or cast-in-place concrete construction either in the fabricating shop or in the field.
1.2
This Standard does not cover welding of plates, angles, or other structural members to one another. This is covered by CSA Standard W59, Welded Steel Construction (Metal Arc Welding).
