Strength Evaluation of Existing Structures
Chapter 20 of the 1995 Code has been extensively revised to provide more specific guidance regarding the strength evaluation of existing structures. If doubt exists that a part or all of a structure meets the safety requirements of the ACI Code, it is mandatory that a strength evaluation be carried out. Existing structures include any completed or partially completed construction the safety of which is in doubt, as well as old and/or deteriorated structures for which the present safety is unknown. In this chapter, the practical application of Code provisions is briefly explained with some practical precautions, but for an in-depth study, the ACI Committee 437 report* is recommended.
