Abstract: The design of anchor system for fastening the equipments and piping systems, etc.. to concrete structure has based on the ACI 349 code in Korean NPPs. But, CCD method of CEB code which was processed in Europe shows that anchor system design according to ACI 349 code has some of overestimated effects in the evaluation of tensile and shear capacity of the real anchor system. Also, according to US NRC SRP published in 1996, US NRC recommended that the anchor system should be designed by test results for each case until ACI 349 code will be newly revised. Moreover, Korean nuclear regulatory institute, KINS asks to follow the requirements of US NRC SRP for design of anchor system in NPPs.
Therefore, in order to accurately evaluate both behavior and tensile capacity of anchor system used in Korean NPPs, actual model tests are carried out in this study. 60 test specimens with cast-in-place headed anchor system which is installed in uncracked and plain concrete test specimens, are manufactured for these actual model tests.
From the results of this study, the discrepancies between the test results and these two design methods, ACI 349 code and CCD method of CEB code, are assessed and applicability of ACI 349 code for design of anchor system are evaluated.
