Abstract:
Load testing has been an integral part of the ACI 318 Standard since the first version was published in 1941. Since 1941, the accepted procedure for load testing has basically involved application of a load to the element for a defined period of time with acceptance (passing) of the load test was based upon a deflection limit and / or recovery of deflections. The load and acceptance criteria have only been slightly changed since the 1963 version of ACI 318. The quasi-equilibrium of load testing procedures was altered with the publication ACI 437.2 “Code Requirements for Load Testing of Existing Concrete Structures”, which allowed the use of both cyclic and traditional static load testing. Adoption of ACI 437.2 into the ACI 562-13 “Code for Repair and Rehabilitation of Existing Concrete Buildings” created a situation where two ACI codes allowed different procedures for load testing of structures. The presentation will describe how three ACI committees worked on the load testing procedures adopted in ACI 318-19, which eliminated the conflict between ACI 318 and 562.
