I have a building near a coastal area that has the lower portion of the metal wall studs heavily corroded. The metal stud track and lower portion of studs have corroded to a point that the web and flanges have lost large sections of their areas. We are in process on investigating what are the possible causes. My question is whether or not shoring of the metal stud wall is required. The Contractor wanted to remove a portion of the studs that was heavily corroded up to a point, clean the remaining rusted section, and apply a corrosion inhibiting coat to the remaining section. A splice joint similar a track splice is the proposed fix to the metal studs. The bottom of the metal studs where originally fastened with TEK screws, so the stud wall behaves as a simple span with little to no moment at the ends. The wall is load bearing. I was wanting to shore up the entire roof that is supported on the wall to perform the fix. The Contractor wanted to repair each stud by providing minimal support. I could check to see where the top plate splices occur and check to see if the areas in which the member is continuous can clear span two stud bays. Studs are spaced at 16" o.c. The roof is also light gage steel studs. I have attached a picture of a section of the wall, pre-inspection.
