Strength Evaluation of Existing Concrete Buildings

Abstract

Background and limitations—Engineering judgment based on rational, scientific principles is critical in the strength evaluation of concrete structures.

Such judgment of a qualified licensed design professional is needed for proper application of relevant code provisions to the case being studied.

An assessment of structural safety can be achieved with the information and data from field investigations, scientific computations based on sound principles, as well as subjective engineering judgment from the licensed design professional.

This is particularly true for structures deteriorated from prolonged exposure to the environment or damaged in an extreme event, such as a fire, earthquake, or explosion.

Similarly, there are no generally recognized criteria for evaluating serviceability of an existing concrete structure
