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.
