Abstract: The American Institute of Steel Construction 1 (AISC) defines serviceability as “a state in which the function of a building, its appearance, maintainability, durability, and comfort of its occupants are preserved under normal usage.” AISC states that, “structural components shall be designed to tolerate corrosion or shall be protected against corrosion that may impair the strength or serviceability of the structure.” The parallel can be drawn that protection from corrosion would increase durability. In early 1900 United States, building façade design was making the transition from mass masonry to curtainwall systems. The introduction of steel framing into façades was a way to reduce the thickness of the masonry, but consideration for the serviceability of the steel was not typically made. As these transitional-framed buildings have aged, the resulting water absorption through the masonry in close contact with the structural steel has resulted in hidden corrosion issues and the phenomenon known as “rustjacking” which can ultimately lead to section loss in the structural steel members. The paper will draw from the author‟s experience in evaluating and repairing transitional buildings and develop an opinion on the expected useful life of steel when encased in masonry with examples of severely corroded steel.
