ACI CODE-437.2-22: Load Testing of Concrete Structures - Code and Commentary

Description

This Code provides requirements for test load magnitudes, test protocols, and acceptance criteria for conducting a load test as a means of evaluating the safety and serviceability of concrete structural members and systems of structures. A load test may be conducted as part of a structural evaluation to determine whether a structure requires repair and rehabilitation, or to verify the adequacy of repair and rehabilitation measures.

Keywords:

acceptance criteria; cyclic loading; load test; monotonic loading; test load magnitude; test protocol.
