This report provides the recommendations of Committee 437 regarding selection of test load magnitudes, protocol, and acceptance criteria to be used when performing load testing as a means of evaluating safety and serviceability of concrete structural members and systems. The history of load factors and acceptance criteria as found in the ACI 318 building code is provided along with a review of other load test practice. Recommended revisions to load factors to be used at this time, additions to load testing protocol, and revisions to acceptance criteria used to evaluate the findings of load testing are provided. Keywords: acceptance criteria; cyclic load test; deflection; deterioration;load test factors; load test protocol; monotonic load test; reinforced concrete; strength evaluation.<\/p>\n
