STANDARD FOR WELDED UNION IN STEEL WIRE MATS

[jobaincosas]

I am designing a MSE Wall structure with steel wire mat as reinforcement. I have these Questions:
1. What is the difference between plain and deformed steel.
2. Out of those two, wich one is more suitable for soil reinforcement.
3. What is the standard for the welded union in Wire mats (tensile force allowable)

ASTM A1064: 8.3.1 describes the shear test value as "...The minimum average shear value in pound-force shall not be less than 35,000 multiplied by the nomimal area of the larger wire in square inches..."

Texas Tech University is currently working on a project for TxDOT to quantify the soil-mesh interaction. The current project is using heavy-coated, hot-dip galvanized materials.

You will probably need a heavy galvanized coated (ASTM A123 is the spec for hot-dip galvanizing), or epoxy coated (ASTM A884), or stainless wire mesh (ASTM A1022) unless you are designing for a very arid environment.

Design for plain and deformed is the same, and in your application, plain smooth wire, post-galvanized is most likely to last longest.
