ABSTRACT

When distress of a structure is evident, it is important to determine the nature of the degradation to select the best restoration strategy. This standard practice provides testing procedures and investigative techniques for the evaluation of masonry- clad steel frame buildings. The investigation and evaluation techniques described in this standard focus on degradation resulting from corrosion of the steel frame.

This standard provides the investigator, corrosion specialist, engineer, or owner a framework for evaluating the corrosion condition of a steel frame building beyond simple visual inspection and basic sounding techniques. Evaluation techniques that identify general and localized corrosion of masonry-clad steel frame buildings are provided.

This standard is intended for use by corrosion specialists, historic architects, structural engineers, and exterior building envelope consultants involved with evaluating corrosion of steel frame buildings and the subsequent effect on the masonry cladding. It also may be useful to owners of historic buildings whose service life may be affected by steel frame corrosion.
