ASTM A706 Reinforcing Bars Technical Information - Page 4

Q24: Any closing comments?
A: To summarize:
- If the rebars for a project do not require controlled tensile properties and/or weldability specify the other types of bars.
- Before completing a design or specifying A706 bars, the prudent designer should investigate local availability
- For use in seismic-resistant structures where welded splices are not going to be used, consider specifying A615 bars with additional requirements for tensile properties. For butt splicing A615 bars, consider the use of mechanical connections.
