This paper presents an experimental study of corrosion-damaged reinforced concrete (RC) columns under eccentric compression. Three RC concrete column specimens, identical in geometry, reinforcing steel bars, and concrete mix, were fabricated. One undamaged control specimen served as the control group, while the other two column specimens underwent corrosion due to chloride ion exposure.

In "Standard Practice for Safeguarding Against Warpage and Distortion During Hot-Dip Galvanizing of Steel Assemblies" steel assemblies and subassemblies fabricated by welding, such as composite structural members, sash, weldments, etc., that are to be hot-dip galvanized after fabrication, are subject to warpage and distortion of the material due to the heating and cooling integral to the galvanizing operation, particularly when it is necessary for the assembly to be dipped more than once to coat the entire surface.

This specification covers sheet steel in coils and cut lengths for porcelain enameling. The compositions and processing of these steels are such that articles for porcelain enameling may be fabricated from them and, under proper conditions, enameled. The steels are furnished as Type I, Type II, and Type III. Type I and Type II are supplied in two designations, Commercial Steel and Drawing Steel. Type III steel is interstitial-free and does not require a designation.
